Part II Plenary Speeches

Plenary Speech 1: Integrated Silicon Photonic Devices for Optical

Interconnections in IT Equipment

Speaker: Prof. Tao Chu, Institute of Semiconductors, Chinese Academy of Sicences, China.

Time: 08:40-09:20, Saturday Morning, August 27, 2016

Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Following the rapid developments of modern information society, data-exchanging of ULSI chip (CPU core-to-core), chip-to-chip (CPU-to-CPU/memory), board-to-board, and rack-to-rack are demanded to be faster and faster by the future Exascale high performance computers, data centers and other IT equipment. However, due to the limits on data rate, time delay, and power consumption of the electrical wiring and communicating, data exchanging encounters the largest problem in speed increasing with the conventional electrical interconnection systems. Optical interconnection based on silicon photonic devices becomes the most promising solution of these issues, due to that silicon photonic devices based on sub-micron silicon waveguides are compact, energy saving, lower cost and CMOS compatible. Scientists have devoted on this research and many novel silicon photonic devices have been developed. In conference, we will introduce the latest progress on a series of silicon photonic devices, including hybrid integrated silicon lasers, high speed silicon modulators module, polarization controlling devices, wavelength MUX/DEMUX devices of AWG and EDG, high speed 32x32 electro-optic and large-scale 64x64 thermo-optic switch matrix, grating couplers and other devices. We will also discuss the applications of integrated silicon photonic interconnecting systems for HPCs, datacenters and other IT systems.

Plenary Speech 2: Design and Optimization of Silicon Photonic Devices

Speaker: Prof. Aziz Rahman, City University London, UK Time: 09:20-10:00, Saturday Morning, August 27, 2016 Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract When the dimensions of an optical waveguide are much smaller than the operating wavelength, unique materials and structural dependent properties can be observed and these recently have been receiving much attention. In this regard, silicon has been particularly attractive as the low-cost and mature


CMOS fabrication technology widely used in the electronics industry can be exploited. The high index contrast of silicon allows light confinement in submicron size waveguides, along with the creation of very compact bends, to allow increased functionality of photonic integrated circuits. However, strong spatial field variation and high field at the dielectric interface demands a full-vectorial approach must be used. A rigorous H-field based full-vectorial modal analysis has been carried out, which can more accurately characterize the abrupt dielectric discontinuity of a high index contrast optical waveguide. As a result, the full-vectorial H and E-fields and the Poynting vector profiles are shown in detail. The modal solutions of silicon nanowires and vertical and horizontal slot waveguides will be presented. Rigorous design optimization of silicon nanowires and slot waveguides and various guided-wave devices, such as power splitters, mode splitters, polarization splitters, polarization rotators, biosensors, SBS and spot-size converters will also be presented.

Part III Invited Speeches

Invited Speech 1: High Density Data Storage System using Collinear Holography

Speaker: Prof. Xiaodi Tan, Beijing Institute of Technology, China


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Holographic data storage systems (HDSS) have been a good candidate for a volumetric recording technology, due to their large storage capacities and high transfer rates, and have been researched for tens of years after the principle of holography was first proposed. However, these systems, called conventional 2-axis holography, still have essential issues for commercialization of products. Collinear HDSS, in which the information and reference beams are modulated co-axially by the same spatial light modulator (SLM), as a new read/write method for HDSS are very promising. With this unique configuration, the optical pickup can be designed as small as DVDs, and can be placed on one side of the recording media (disc). In the disc structure, the preformatted reflective layer is used for the focus/tracking servo and reading address information, and a dichroic mirror layer is used for detecting holographic recording information without interfering with the preformatted information. A 2-dimensional digital page data format is used and the shift-multiplexing method is employed to increase recording density. As servo technologies are being introduced to control the objective lens to be maintained precisely to the disc in the recording and reconstructing process, a vibration isolator is no longer necessary. Collinear holography can produce a small, practical HDSS more easily than conventional 2-axis holography. In this paper, we introduced the principle of the collinear holography and its media structure of disc. Some results of experimental and theoretical studies suggest that it is a very effective method. Keywords holographic data storage system (HDSS), holography, optical memory, volumetric


recording, optical disc, high density recording.

Invited Speech 2: Single Nanoparticle Detection Using High-Q Optical

Microcavities

Speaker: Prof. Yunfeng Xiao, Peking University, China


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Confinement and manipulation of photons using microcavities have triggered intense research interest in both fundamental and applied photonics for more than one decade. Prominent examples are ultrahigh-Q whispering gallery microcavities which confine photons by means of continuous total internal reflection along a curved and smooth surface. The long photon lifetime, strong field confinement, and in-plane emission characteristics make them promising candidates for enhancing light-matter interactions on a chip. In this talk, I will focus on the single-nanoparticle detection by using whispering gallery microcavities, which is highly desirable for applications in various fields, such as in early-stage diagnosis of human diseases and in environmental monitoring.

Invited Speech 3: Study on Temperature Features of a

Diode-Pumped Alkali Laser (DPAL)

Speaker: Prof. You Wang, Southwest Institute of Technical Physics, China


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract With high Stokes efficiency, good thermal performance, narrow linewidth, compact size, non- toxic system, etc., a diode-pumped alkali laser (DPAL) becomes one of the most hopeful high-powered laser sources of the next generation and has been rapidly developed in the last ten years. However, the thermal effects will bring about some serious problems in nonuniformity of the temperature distribution for a high-powered DPAL system because the thermal conductivity of a gas-state medium is so small that the generated heat cannot be transferred outside efficiently. Unlike a conventional electrically-excited gas-state laser, the number densities of alkali vapors and buffer gases (generally being helium and small hydrocarbons such as methane and ethane) in a DPAL often exhibit inhomogeneous distributions resulting from the temperature gradient inside a vapor cell.


Actually, the inhomogeneous of the alkali vapor directly influences the output performances of a DPAL. Studying the temperature distribution in the cross-section of an alkali-vapor cell is critical to realize high-powered DPAL systems for both static and flowing states. In this report, a theoretical algorithm has been built to investigate the features of a flowing-gas DPAL system by uniting procedures in kinetics, heat transfer, and fluid dynamic together. The thermal features and output characteristics have been simultaneously obtained for different gas velocities. The results have demonstrated the great potential of DPALs in the extremely high-powered laser operation.

Invited Speech 4: Ways of Precision Photon Status Sensing for Future Super

Resolution Medical Imaging

Speaker: Prof. Xuefeng Liu, Nanjing University of Science & Technology, China


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract The simple mimic of human eye, grey scale and color tone mapping formed through photon number counting and energy measurement are direct optical imaging that suffer from losing of vital information due to nearfield evanescence and transmission diffraction. Direct imaging has a theoretical resolution limit of 1/4 wavelength, which has been seeking to break in a few world leading research centers and of cause also including RINRO (Research Institute of Nano-Resolution Optics) since the beginning the new millennium. This paper present a newly developed theory and method named photon status PIMI (Parametric Indirect Microscopic Imaging) for optical super resolution with the particular application in biomedical in vivo measurement. Photon status PIMI defies the usual working principle for super resolution, it does not just concerning the refinement of the measuring point size, photon numbers and photon energies, and instead, it makes the great effort on how to collect the high frequency evanescent wave and precisely calculate the parameters of average photon status after coupling with the Sample under Test (SUT). As an inevitable consequence, photon status PIMI can calculate photon wave parameters such as spatial phases, spatial azimuths, Stocks, degree of polarization across all photons collected from one point to the accuracy much higher than photon number counting. These photon status parameters can be used to differentiate two closely ranged neighboring points in the SUT so that spatial resolution can be considerably improved. Differing from measuring point size refining theory and methods, such as confocal microscopy gaining the scaling law of N^(-1/4) (N is the total photon number), also STED, STORM and PALM and so on fluorescent point control methods collecting the resolution scaling down to N^(-1/2), photon status PIMI, with the added photon status feature useful for the effective differentiation in the nanometer space, can gather the break through N^(-2) super resolution scaling. We will show the edge of a cell can be resolved to the resolution of 10nm in comparison with that of 300nm measured in conventional microscopy.


Invited Speech 5: Study on fiber property of the Chinese meridian and Apply the

fiber coupler theory of photoreceptors to explain color version

Speaker: Prof. Anhui Liang, Guangdong University of Technologies, China


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract TBD

Invited Speech 6: Silicon-based microphotonic structures and devices

Speaker: Prof. Wei Jiang, Nanjing University, China

Time: 14:00-14:30, Saturday Afternoon, August 27, 2016

Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Silicon photonics has made great strides in the last decade as it can take advantage of the low-cost manufacturing platform offered by the CMOS technology. In future development, compact devices and high density integration will be key to demonstrating the value of silicon photonics. Silicon-based microphotonic structures can be introduced to enable compact devices and high-density integration. Several examples will be presented. Silicon-based dual-racetrack micro-resonators have potential applications in advanced modulation formats such as quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM). The coherent amplitude and phase characteristics of dual-racetrack micro-resonators have recently been studied. Large phase variation range has been observed, which indicates the feasibility of such structures for advanced modulation formats. High-density waveguide integration is becoming increasingly important in recent years partly due to needs in space-division multiplexing and optical phased arrays. The fundamental challenge in achieving high integration density is the high crosstalk as the waveguide spacing is reduced to the wavelength scale. Recently, waveguide superlattices have been introduced to construct high-density waveguide arrays at half-wavelength pitch with very low crosstalk. The underpinning physics and design rationale of low-crosstalk waveguide superlattices will be presented. Potential applications of our work in optical interconnects, space-division multiplexing, mode-division multiplexing, wavelength-division multiplexing, and optical phased arrays will be discussed.


Invited Speech 7: An Optical Fibre Sensor for Ammonia Gas Detection in the

Ultra Violet Region

Speaker: Prof. Elfed Lewis, University of Limerick and IEEE Sensors Council, USA


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract A novel optical fibre sensor (OFS) is described for the monitoring of low level atmospheric ammonia concentrations. The measuring technique employed is based on a differential optical absorption approach, which uses a broadband optical source to include Ultra Violet (UV) wavelengths, optical fibres suitable for ultraviolet/visible (UV/VIS) transmission and a miniature spectrometer for UV/VIS detection. This novel technique for the detection of ammonia is shown to be capable of monitoring concentrations as low as 1 part per million (ppm) without any noticeable cross-sensitivity. The sensor was operated over a number of hours in-situ in an agricultural cattle enclosure and simultaneously with a commercially available ammonia sensor. Results shown herein demonstrate the effectiveness of the developed sensor to operate within the environment safely and accurately, recording concentration levels in the range 0 to 2 ppm.

Invited Speech 8: Fiber gratings and their applications in all-optical signal

processing

Speaker: Prof. Xuewen Shu, Wuhan National Laboratory for Optoelectronics, China Time: 15:00-15:30, Saturday Afternoon, August 27, 2016

Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Fiber gratings are periodic or quasi-periodic structures formed in optical fibers, which provide a very attractive platform for all-optical signal processing directly in optical fibers. The distinct advantages of fiber grating based signal processors include full compatibility with optical fiber systems, low insertion loss, compact size, ultrafast processing speed and tailorable bandwidth. In this presentation, we will first give an overview of fiber grating technology and then review our past and recent research on the design and fabrication of different complex fiber grating structures for all-optical signal processing.


Invited Speech 9: Recent Advances in Chip-Scale Optical Signaling and

Processing on a Silicon Platform

Speaker: Prof. Jian Wang, Huazhong University of Science and Technology, China


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Silicon-on-insulator (SOI) is an attractive low cost integration platform for photonic integrated circuits (PICs) facilitating chip-scale optical signaling and processing. In this talk, we review recent advances in chip-scale optical signaling for interconnects and chip-scale optical pocessing for grooming functions. Using the fabricated silicon photonic devices, we demonstrate chip-scale terabit signaling using WDM OFDM m-QAM signals, chip-scale polarization and wavelength demultiplexing of OFDM m-QAM signals, chip-scale mode (de)multiplexing of OFDM m-QAM signals, chip-scale wavelength conversion of OFDM m-QAM signals, chip-scale optical data exchange of m-QAM signals, chip-scale high-dimensional optical computing using m-PSK signals, and chip-scale optical signal regeneration of PAM4 signals.

Invited Speech 10: Failure Criterion of Organic Photovoltaic Cells in Aqueous

Solutions

Speaker: Dr. Khaled Habib, Materials Science and Photo-Electronics Lab., IRE Program, EBR Center, Kuwait


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract A criterion of the degradation/oxidation susceptibility of organic photovoltaic (OPV) cells in aqueous solutions was proposed for the first time. The criterion was derived based on calculating the limit of the ratio value of the polarization resistance of an OPV cell in aqueous solution (Rps.) to the polarization resistance of the OPV cell in air (Rpair.). In other words, the criterion; lim (Rps. /Rpair )=1 was applied to determine the degradation/oxidation of the OPV cell in the aqueous solution when Rpairbecame equal (increased) toRps.as a function of time of the exposure of the OPV cell to the aqueous solution. This criterion was not only used to determine the degradation/oxidation of different OPV cells in a simulated operational environment, but also, the criterion was used to determine the electrochemical behavior of OPV cells in deionized water and a polluted water with fine particles of sand. The values of Rpswere determined by the electrochemical impedance spectroscopy (EIS) at low frequency. In addition, the criterion can be applied under diverse test conditions with a predetermined period of


OPV operations. Keywords: Degradation/Oxidation, Organic Photovoltaic (OPV) Cells, Power Conversion Efficiency (PCE) ; Electrochemical Impedance Spectroscopy (EIS), Aqueous Solutions.

Invited Speech 11: Millimeter-Wave/Terahertz Antennas and Integrated Circuits

for Imaging and 10Gbps Communications

Speaker: Prof. Sanming Hu, Southeast University, China


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Millimeter-wave (mmWave) and terahertz (THz)technologies have shown great potential for numerous applications including high-data-rate communication and biomedical imaging. Nevertheless, the realization and development of a compact, low-cost, and silicon-based mmWave/THz system is limited by some technical bottlenecks. This talk reviews our research work on the silicon-based mmWave/THz antennas with circuit chips for 10Gbps communications and biomedical imaging. This talk also explores emerging silicon processes (such as 3D through-silicon via) as well as new materials (including graphene) for mmWave/THz systems including antennas and chips.

Invited Speech 12: Acoustic Phase Cancellation on Broadband Ultrasonic

Speaker: Prof. Yi-Xian Qin, Stony Brook University, USA


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract Quantitative ultrasound has been developed to evaluate trabecular bone mineral contents and structural integrity. The ultrasound parameters, i.e., normalized broadband attenuation (nBUA), have been widely used as indicators for bone health status. However, the reproducibility and accuracy of nBUA are influenced by the phenomena of phase cancellation. A 2-D array scanning ultrasound measurement system was developed for bone assessment using a receiver with an ultra- small aperture size to limit the phase cancellation effects on the physical receiver itself. The objectives of this study have two folds, 1) to accurately investigate the effects of phase cancellation and receiver aperture size on BUA calculation using an ultra-small receiver (aperture size: 0.2 mm) in a newly developed 2-D synthetic array-system, and 2)


to evaluate the effects of phase cancellation on human trabecular bones. The tests of ultrasound BUA and micro-CT on the trabecular bone cylinders with a diameter of 25 mm. Both phase sensitive (PS) detection and phase insensitive (PI) detections were performed. Results show that phase cancellation does have a significant effect on BUA (e.g., PS nBUA is 8.1% higher than PI nBUA). Receiver aperture size also influences the BUA reading for both PI and PS detection and smaller receiver aperture tends to result in higher BUA readings. The data indicated that the average nBUA is 24.8±9.5 dB/MHz/cm and 19.2±5.5 dB/MHz/cm for PS and PI respectively. PS nBUA is 28.5% higher than PI BUA, which PS-nBUA can explain 81.2% of the variability in PI nBUA. Both PI-nBUA and PS-nBUA are highly correlated with BV/TV (R=0.911 and R=0.898, p<0.0001), and the Young’s modulus (R=0.9061 and R=0.822 p<0.0001), respectively.

Invited Speech 13: Optical and electronic properties of monomers of eumelanin: a

DFT and TD-DFT computational study

Speaker: Prof. Giancarlo Cappellini, Cagliari University, Italy


Location: Tongji Room(通济厅)，3rd Floor, Ramada Xi’an Bell Tower Abstract We report a systematic investigation on the electronic and optical properties of four monomers which are elementary constituents of some the protomolecules of eumelanin. Eumelanin is the most important form of melanin which is one of the most universal natural pigments in living organisms. For the isolated monomers we performed all-electrons Density Functional Theory (DFT) and Time Dependent DFT (TDDFT) calculations with a localized Gaussian basis-set. For each monomer we deter-mined a series of molecular properties, namely electron a nities, ionization energies, fundamental energy-gaps, optical absorption spectra, andexciton binding energies. We discuss moreover the possible implications of the above electronic and optical properties of the single monomers with respect to the properties of a recently proposed tetrameric protomolecule of eumelanin.

Abstract

Laser ceramics have been well-developed with

remarkable advantages allowing for high doping,

large-size sample fabrication, homogeneous dopant

distribution, optical grade post-processing of low

cost, low-threshold broadly tenability, as well as

sophisticated but convenient engineering of

multilayer structures, which are regarded as

promising substitutes for the next generation of laser

gain media [1,2]. In particular, effective thermal

management of ceramic laser can be achieved by

using multilayer ceramics with different doping,

which was suitable for the application of a

high-power laser [3]. Nowadays, solid-state lasers

continue to occupy a prominent place among

different kinds of fields. In order to meet the

challenging requirements in the areas of laser power,

beam quality, efficiency, size and weight, it is

essential to optimize the structural designing of laser

gain media. Planar waveguide structure (PWs) has

peculiarities of low lasing thresholds, high gain, high

heat transmission and optical confinement with

respect to the traditional uniform bulk laser system,

which makes waveguide lasers suitable for high

power and compact devices. Taking the advantages

of both the RE:YAG ceramics and the planar

waveguide structure, it is very promising to construct

Name: Yonggang Wang

Affiliation: Shaanxi Normal University


Abstract

Some novel solution saturable absorber (SA) such as

black phosphrous (BP), WS2 and MoS2 are

fabricated by liquid-phase-exfoliated method and

used for passively Q-switched Nd:YVO4 laser

successfully. Compared with traditional solid SA,

solution SA possesses more excellent optical

transparency and higher damage threshold. The

shortest pulse duration are measured to be 3 ns.

Similar solution absorbers are used in mode locking

of fiber lasers. The SA is fabricated based on a

D-shaped fiber (DF) embedded in Wide band

material solution. Such absorbers have virtues of

good antioxidant capacity, excellent scattering

resistance, high heat dissipation and high damage

threshold. Femtosecond laser pulses and picoseconds

laser pulses are obtained in Er doped fiber lasers and

Yb doped fiber lasers.

of Sciences


Abstract

Waveform Nonlinear Optics aims to study and

control the nonlinear interactions of matter with

custom-tailored sub-optical-cycle waveforms. In this

regime, the time-evolution of the optical electric field

deviates strongly from a sinusoidal carrier-wave

oscillation with in a single cycle of light, so that the

usual approximations of nonlinear optics break down,

and new phenomena and opportunities arise.

Specifically, a novel multi-channel parametric

synthesizer driven by a KW-level Yb pump-laser will

overcome pulse-energy and average-power

bottlenecks for advanced applications. Such intense

optical high-repetition-rate waveforms

custom-sculpted within an optical cycle open up new

horizons for controlling strong-field interactions in

atoms, molecules, solids and nanostructures.

Title: Ultra-broadband WS2-based saturable

absorbers for erbium-doped fiber lasers

Name: Wenjun Liu

Affiliation: Beijing University of Posts and

Telecommunications


Abstract

Saturable absorbers (SAs) can be used to generate

ultrashort pulses in fiber lasers with self-starting

operation and environmentally stable [1]. Compared

to other SAs, the tapered fiber SAs have higher

damage threshold, longer interaction length, and

wider spectral width [2]. In this paper, the fiber-taper

WS2-based SAs have been used in erbium-doped

fiber (EDF) lasers as illustrated in Fig. 1. The SAs

have been fabricated by depositing the WS2 on the

tapered fiber with the pulsed laser deposition method.

The length of the fiber-taper is 3 mm, and the waist is

12 μm. The saturable intensity is at of 34 MW/cm2,

the modulation depth is 25.48%, and the

non-saturable loss is 61% in Fig. 2. By rotating

HWPs and QWPs in Fig. 1, the EDF laser can be

mode-locking at 1540 nm. The fundamental cavity

repetition rate is 135 MHz, the electrical signal to

noise ratio (SNR) is 93 dB, and the timing jitter is

280 fs in Fig.3. The pulse duration is 67 fs, and the 3

dB spectral width is 114 nm, which is the widest

spectrum for the same type fiber lasers. By using

comparison experiment, we summarize the

corresponding parameters for the different

mode-locking scheme in Table 1. Those results

demonstrate that the fiber-taper WS2-based SAs are

promising devices for the ultra-broadband pulse

generation.

Title: Fabrication of Phase-shifted fiber Bragg

grating by using femtosecond laser irradiation

Name: Tao Chen

Affiliation: School of Electronics & Information

Engineering, Xi’an Jiaotong University


Abstract

Phase-shifted fiber Bragg gratings (PSFBG) have

found wide applications in optical fiber switch,

distributed feedback lasers, optical fiber filter,

wavelength division multiplexing and so on. Usually,

fabrications of PSFBG involve an elaborate setup. In

addition, PSFBG could only be fabricated in

photosensitive fibers. In this paper, we demonstrated

a method of fabricating PSFBG by using

femtosecond laser irradiation. The phase-shifted

zone was formed by using femtosecond laser raster

scanning in FBG. Phase shift could be varied by

changing the area of femtosecond laser scanning

zone and laser power. When the scanning length

along fiber axis was fixed, phase shift could be

accurately varied from 0 to 2π by control the

scanning line numbers. In addition, phase shifted also

increased with the increase of the length of the

phase-shifted zone. With the increase of laser power,

phase shift of PSFBG also increased, but loss was


also increased. This method was meaningful for

fabricating PSFBG in fibers without photosensitivity.

Abstract

Light beams with a helical phase front which possess

an orbital angular momentum (OAM) along their

direction of propagation, can induce optical vortex

(OV) as focused. As a novel optical phenomenon,

OV beams hold the promise in various physical

mechanical, and technological appli-cations, such as

optical manipulation, optical communication,

quantum information, and astronomy. Over the past

decades, efforts have been made to fabricate and

design OV beams. Over the past decades, efforts have

been made to fabricate and design OV beams,

including the geometric method, hologram fork

dislocation grating, spiral phase plate, hollow optical

fiber, and changing optical parametric oscillator. The

above-mentioned methods are typical approaches to

obtain OV beams and greatly broaden their

applications.

Here, we fabricated spiral phase plate (SPP) on the

surface of Lithium niobate (NL) and spiral zone plate

in LN with femtosecond laser direct writing

(FsLDW). The optical properties were demonstrated

in the experiment, which is consistent with the

theoretical simulation. This method can greatly

simplify the OV generator and improve the

integration of optical systems. Our findings open up a

new avenue to realize highly integrated optical

element and offer great convenience to their practical

applications in optical manipulation and quantum

Title: Sapphire based UV micro-optics elements


and wet etching

Name: Qiankun Li

Affiliation: Jilin University


Abstract

Sapphire is one of the most widely used optical

materials for its excellent optical transparency from

Mid-IR to UV and high hardness, thermal and

chemical stabilities. For example, it can be used for

never-worn optical window of cameras and watches,

and especially harsh-condition-applicable windows

of military infrared devices and space optics.

However, some advantages and features of sapphire,

such as chemical inertness and the largest hardness

among oxide, make it difficult to process

mechanically or chemically on the other hand.

Traditional mechanical polishing process has

limitations of high side damage, frequent rupture and

tool wearing. As for chemical etching, etching speed

is usually slow and changes with crystal lattice

orientation, resulting in problems of processing

efficiency and controllability. Lithography and

nano-imprint could fabricate antireflec-tive

sub-wavelength gratings on sapphire for light

extraction efficiency enhancement, compared with

direct laser writing, they have many drawbacks such

as high costs, mask depended and com-plicated

process. Here, we report sapphire-based Fresnel zone

plate (FZP) and Dammann gratings (DGs), which is


(FsLDW) assisted with subsequent wet etching. With

this method, we solved the problem of high surface

roughness caused by ultrafast femtosecond laser

processing. Ultraviolet light focusing and imaging

can be easily achieved by fabricated Fresnel zone

plate. DGs that generated 2 × 2, 3 × 3, 4 × 4, and 5 × 5

spot sources in the fan-out as designed, and exhibited

diffraction efficiency of 52%, 40%, 29%, and 53%,

respectively, comparable with theoretical values. Due

to the high material hardness, thermal and chemical

sta-bilities of sapphire, such sapphire FZP may have


great potential in UV imaging under some harsh

environments. And sapphire-based DGs show great

potential in UV beam shaping, UV beam splitting and

laser parallel micro-processing.

circular Airy beams can be effectively manipulated

by different dynamic linear potentials. We find that

the autofocusing effect can be either strengthened or

Title: Simulation of Chirped Pulse Propagation

in Silicon Nanowires: Shape and Spectrum

Analysis

Name: Hassan Pakarzadeh

Affiliation: Department of Physics, Shiraz

University of Technology, Shiraz, Iran


Abstract

In this paper, we simulate the propagation of chirped

pulses in silicon nanowires by solving thr nonlinear

Schrödinger equation (NLSE) using the split-step

Fourier (SSF) method. The simulations are

performed both for the pulse shape (time domain)

and for the pulse spectrum (frequency domain), and

various linear and nonlinear effects changing the

shape and the spectrum of the pulse are analyzed.

Owing to the high nonlinear coefficient and a very

small effective-mode area, the required length for

observing nonlinear effects in nanowires is much

shorter than that of conventional optical fibers. The

impacts of loss, nonlinear effects, second- and

third-order dispersion coefficients and the chirp

parameter on pulse propagation along the nanowire

are investigated. The results show that the sign and

the value of the chirp parameter have important role

in pulse propagation so that in the anomalous

dispersion regime, the compression occurs for the

up-chirped pulses, whereas the broadening takes

place for the down-chirped pulses. The opposite

situation happens for up-and down-chirped pulses

propagating in the normal dispersion regime.

Abstract

While the signal field+ASE noise pass through a span

of transmission fiber, a dispersion compensation

grating and a fiber amplifier(with the generation of

ASE noise), the nonlinear Fokker-Plank equations,

describing the field’s probability transforms, are

established and solved. Based on these statistical

theories, the probability distributions of the signal

+ASE noise field through 50km NZDSF, a dispersion

compensation grating and a fiber amplifier link, are

obtained. The dispersion and nonlinear effects in

transmission fiber induce frequency offsets in the

probability distribution of field and they can not be

dissipated by dispersion compensation. The

generation of ASE noise in the amplifier will

accelerate this frequency offset.

A novel scheme which can realize high-speed optical

Abstract

The proper choice of optomechanical components

along with alignment techniques is vital to the

successful implementation of lens positioning and

mounting. In general there is a trade-off between lens

positioning accuracy and manufacturing cost. In

order to achieve optimal precision-to-cost ratio a

careful optomechanical design together with accurate

alignment and assembly is necessary. This paper

presents a lens positioning and mounting in a few

microns accuracy using a kinematic mount module.

The optomechanical design of the kinematic mount

module and the associated fixtures based on the

simulation study of components sensitivity are

presented. The processes for alignment and assembly,

which separate decenter from tip-tilt, are developed

and presented. Finally, the prototypes are created and

testing results are presented. The optomechanical

design that allows the separation of decenter from

tip-tilt considerably simplifies the positioning and

assembly process and reduces the cost for mass

production.

Title: Four-Wave Mixing of Extreme-UV

Pulsewith Rare Gas Ion

Name: Hsuhsin Chu

Affiliation: National Central University


Abstract

In the past decades, several kinds of coherent

extreme-UV (EUV)/x-ray sources have been

developed with ultrashortdurations and ultrahigh

intensities, such as x-ray free electron laser and

high-harmonic generation (HHG). Therefore, it is

possible to explore the science of EUV/x-ray

nonlinear optics now. There are severalEUV/x-ray

nonlinear interactions have been demonstrated. For

example, non-collinear wave mixing of EUV


andoptical pulses is obtained in high-harmonic

generation process [1]. Four-wavemixing with

EUVtransient gratings on SiO2 [2], x-ray/optical

sum-frequency generation in diamond [3], and x-ray

second harmonicgeneration in diamond [4] have

been achieved by using EUV/x-ray free electron

lasers. In these experiments, the measured

conversion efficiency range from 10−11 to 10−7.

In this presentation, we propose to use rare gas ions

as the interacting medium, which canbe prepared by

using an intense near-IR (NIR) pulse focused onto a

rare gas jet. The intense NIR pulse ionizes thegas

atoms to a proper ionization stage through

optical-field ionization at its front edge, then mixes

with the followingEUV pulse by the ions. If the

ionization potentials of the remaining electrons in the

ion are larger than the EUVphoton energy,

photoionization will not occur and absorption of the

EUV pulse can be greatly reduced. However,

theremaining electrons can still provide the required

response for nonlinear wave mixing.

Insuch kind of isotropic system, third-order

nonlinearity is the dominant nonlinearresponse.

Therefore, we plan to demonstrate the four-wave

mixing(FWM) of one EUV photon and two NIR

photons. We numerically calculatethe third-order

nonlinear polarizability of Ar3+ ions with the

combinationof R. D. Cowan’s Atomic Structure

Code [5] and Wigner-Eckart theorem. As a result of

that the ionization potential of the forth electron of Ar

is 59.81 eV, the Ar3+ ion canbe used for the EUV

waves with wavelengths longer than 20.7 nm.

Thecalculation result ranges from 10−65 to 10−61

coul-m4/volt3 for the interaction of one EUV(30–45

nm) photon and two NIR (810 nm) photons. Then,

we propose an experimentwith a 1-μJ EUV pulse (45

nm) and a 50-mJ NIR (810 nm) pulse mixed in

a2-mm Ar gas jet. The expected FWM output (40.5

nm) is about 1 nJ, corresponding toa conversion

efficiency of 10−3. As a result of thatthe technique of

NIR pulse waveform control is well-developed, it can

be transferred to EUV pulse though theproposed

FWM process. Therefore, this would not only be a

demonstration of EUV wave mixing, but also be a

newmethod of EUV waveform control.

Abstract

Nano scaled one dimensional oxide semiconductors

are responsive materials for electric devices. Zinc

oxide (ZnO) nanorods are demonstrated to be

applicable for optoelectronic devices such as

ultraviolet (UV) laser(1), direct current nano

generators(2), semiconductor sensitized solar cells(3)

and active matrix liquid crystal display (4). In our

previous studies, ZnO nanorods were also use to

enhance light emission intensity of Powder

Electroluminescence.

Hydrothermal synthesis is a simple and economized

approach, which enables the large production of ZnO

nanorods at low temperature. In this method, ZnO

nanorods are grown on seed layers prepared on the

substrate (Fig.1). In the previous study on the

formation of ZnO nanostructures through

hydrothermal synthesis, the characteristic of ZnO

seed layers is suggested to affect strongly on the

structural parameters of produced

nanostructures(5)(6).

Here, we investigated the effect of seed layers on

ZnO nanorods through the fabrication of ZnO

nanorods on ZnO seed layers with controlled

thickness and further annealing. ZnO seed layers

were fabricated on c-axis sapphire substrate by

Magnetron sputtering. The prepared layer was

annealed at N2 atmosphere. The flatness and

crystallinity of ZnO seed layer were observed to be

improved by annealing at higher temperature and

increasing thickness of the seed layer. Then, ZnO

nanorods were fabricated on ZnO seed layers by

hydrothermal synthesis. As a result, we found that

size and filling rate of ZnO nanorods were influenced


by crystallinity of seed layer.

By tailoring seed layer condition, desired

morphology of ZnO nanorods will be obtained, and

consequently improvement or optimization of

enhanced EL emission will be realized.

spin coating method on the ITO/quartz substrate. on

the seed layer ZnO nanorods were grown by

hydrothermal synthesis method. As a reference

phosphor layer and a dielectric layer were fabricated

by spin coating on the respective substrate, then a

back electrode of silver was formed by the vacuum

measurement of the transmission spectrum was

performed by UV-visible spectrophotometer. And the

intensity of light emission was measured from the

quartz substrate side.

Voltage-Emission intensity characteristic of each EL

devices are shown in the Fig.2. The frequency of the

Abstract—The report emphasizes the importance of

the study of terahertz radiation biological effects as

another direction in the creation of diagnostic and

therapeutic methods, along with terahertz imaging

and terahertz spectroscopy. Therapeutic and

diagnostic use of laser terahertz radiation based on

the results of pre-conducted fundamental research of

biological effects of terahertz radiation at the

organismic, cellular and molecular levels presents.

Keywords—terahertz radiation; biologic effects;

treatment; diagnostics.

I. TREATMENT

The investigation of terahertz effects on organism

level lets to use the terahertz radiation as treatment

factor. It was demonstrated the dose-dependent

influence of terahertz radiation on rat spleen cell

production of antibodies to sheep red blood cells and

on migration ability of B-lymphocytes in antigen

presence. In addition it was demonstrated the

dose-dependent influence of THz radiation on stage

of bone regeneration in rats with experimental defect

of femur. These results allowed to use the


gas-discharge HCN laser (0,89 THz) for treatment

traumatic and degenerative disorders in bone and

cartilage tissues. Treatment of rats with experimental

mechanical damage to the skin demonstrates the

decrease in wound area. Terahertz irradiation of

patients with post-operative and post-traumatic

mechanical skin lesions demonstrates the next results

of treatment: the acceleration of wound healing, the

prevention of post-operative and post-traumatic

suppuration of wounds, the increase in contraction of

wound surface, the stimulation of regenerative ability

and optimization of cellular composition of wound

exudate. Terahertz irradiation of volunteers with

spinal osteochondrosis induces positive dynamics of

metabolism indices in the cartilage (normalization of

chondroitin sulfate and glycosaminoglycans serum

levels). Experimental treatment of grafted Guerin

carcinoma by terahertz radiation demonstrates the

reduction of tumor growth.. Degree of tumor growth

reduction after terahertz treatment and x-rays

treatment are identical.

II. DIAGNOSTICS

Terahertz radiation causes more pronounced increase

of mitogen-induced proliferation of lymphocytes. It

was found that among healthy persons there are the

individuals with initially low proliferative activity of

lymphocytes. Responses of lymphocytes to terahertz

irradiation were different. There is or the absence of

proliferous potential ability or pronounced

proliferous potential ability. In the first case there is

an insufficiency of immune system , in the second

case – the lesion of regulation of immune system. It

may be used at asymptomatic and early stages of

different diseases, which induced by immune

insufficiency: all diseases of internal organs,

oncologic diseases, autoimmune diseases etc. It can

be a base for creating the diagnostic test to evaluate

the ability of lymphocytes to proliferation and apply

it to identify individuals at the early stages of

different diseases, which induced by immune

insufficiency: all diseases of internal organs, different

hematological diseases, oncologic diseases,

autoimmune diseases etc. This may facilitate the

identification of trends to failure of the immune

system in healthy individuals.

It was demonstrated that terahertz radiation results in

a viability reduction in part of irradiated lymphocytes.

This is tested by the appearance in cytoplasm the

colorant penetrating only nonviable cells. Based on

this result it is possible to create the diagnostic test

for identifying of potentially nonviable lymphocytes

and used it to identify healthy individuals which have

the early stages of various hematological disorders,

different variations of immune system disturbance

and other diseases that lead to such violations.

Terahertz radiation induces a specific state, which in

combination with provoking factor reveals to

morphological or functional abnormalities which are

undiagnosable by traditional methods. The study of

terahertz radiation influence on membrane stability

of red blood cells demonstrates that terahertz

radiation does not influence spontaneous hemoglobin

output, but increases the hemoglobin output induced

by water adding to isotonic buffer solution

(hypoosmotic hemolysis). This effect is increased if

the concentration of sodium chloride solution is

decreased. Terahertz radiation causes pronounced

shorting of duration of full hypoosmotic hemolysis.

Results of these experiments can be a premise for

creating the diagnostic test for identifying a tendency

to disturbance of red blood cell membrane resistance

in healthy individuals for recognition of early stage

of various hematological, nephrological,

endocrinological and other diseases which are

associated with impaired membrane status of these

cells.

Title: Tip-enhanced Near-field Optical

Microscopy Based on a Plasmonic Lens/ Probe

Abstract

Tip-enhanced near-field optical microscopy is a


promising scanning probe technique for exploring

near-field optical properties of individual objects and

structures on the nanoscale. It is capable of obtaining

corresponding topographical and optical information

with resolution beyond the diffraction limit and

grants remarkable localized optical signal

enhancement. This technique uses a sharp metallic

tip regulated in the near-field of a specimen’s surface,

which is illuminated with a proper excitation field

meeting the excitation conditions of the wave-vector

matching. The local optical field interacted with the

specimen in the vicinity of the tip apex is effectively

enhanced. In this technique, the signal enhancement

near the antenna is attributed to the excitation of

localized surface plasmons and the lighting-rod

effect. Typically, a tip-enhanced near-field optical

microscope is composed of a scanning probe

microscope, excitation/ collection optical

configuration, and a detection device. In this

technique, how to optimize the tip-excitation field

coupling to improve the detection sensitivity is of

crucial importance and receives great research

attentions.

In this work, two kinds of methods are presented to

improve the signal to noise ratio of tip-enhanced

near-field optical microscopy by both strengthen the

near-field optical signal enhancement and reducing

the far-field background noise. First, a tip-enhanced

near-field optical microscope based on a plasmonic

lens is investigated. A symmetry-breaking strcture

plasmonic lens is specifically designed for focusing

the surface evanescent wave and generates a

longitudinal field dominated excitation field. The

focusing property of the longitudinal field by the

plasmonic lens is theoretically simulated and

experimentally investigated. It is demonstrated that

the plasmonic lens is suitable for providing the

longitudinal field excitation foe local field

enhancement on a tip antenna. Then, the plasmonic

lens is utilized in the excitation configuration of the

tip-enhanced near-field optical microscope to replace

a conventional objective lens. Second, a plasmonic

probe which consisted of a taper cylinder tip and a

couple of curved nanoslits on the probe base was

designed. It is suitable to be used in top-illumination

mode tip-enhanced near-field optical microscope to

isolate the focused near-field excitation at the probe

apex from the contribution of the far-field

illumination. The field enhancement and the

confinement performance of the probe were

investigated using three-dimensional

finite-difference time-domain method. The structure

of the probe was optimized and fabricated with FIB

method. The field enhancement performance of the

plasmonic probe was theoretically simulated and

experimentally detected.

mesa type photodiodes, not only the bulk defect but

mesa edge of the device destroy the optical properties

of the detectors. Low surface recombination is

disks, credit cards, speakers, coolers, automatic doors,

and many other devices can be observed on a daily

basis. The structure and morphology of as-prepared

Co3O4 nanoparticles were characterized by X-ray

diffraction (XRD), transmission electron microscopy

(TEM) and vibrating sample magnetometer (VSM).

The TEM images showed that the product

nanoparticles consisted of dispersive quasi-spherical

particles with a narrow size distribution ranged from

5 to 15 nm and an average size around 10 nm. The

magnetic measurements confirmed that the Co3O4

nanoparticles show a little ferromagnetic behavior

which could be attributed to the uncompensated

surface spins and finite size effects. The

ferromagnetic order of the Co3O4 nanoparticles is

raised with increasing the decomposition

temperature.

Title: The Study of Structural and Magnetic

Prop-erties of NiO Nanoparticles

Name: Fardin Taghizadeh

Affiliation: Department of Physics, College of

Sciences, Yasouj University, Yasouj 75914-353,


Abstract

Nickel Oxide (NiO) is an important transition metal

oxide with cubic lattice structure. Among the

magnetic nanoparticles, fabrication of nickel

nanoparticles is often more difficult than the other

particles. This is because they are easily oxidized. To

achieve pure nickel nanocrystals, numerous methods

have been conducted in organic environments in

order to prevent formation of hydroxide or oxidation.

In the present work, we report the synthesis of NiO

nanoparticles.

Magnetic properties of NiO nanoparticles with

different sizes and at different temperatures are

compared. The phase structures, particle sizes and

magnetic properties of NiO nanoparticles have been

characterized by X-ray diffraction, TEM images and

vibrating sample magnetometer (VSM).

We collected the experimental data reported in the

literature, for the same conditions, and after fitting,

extrapolating and doing some calculations. The

magnetization for smaller nanoparticles are bigger,

for the samples we consider here. This difference

could be explained by the difference of surface

volume ratio of nanoparticle which shows the

contribution of the paramagnetic surface is more

important with respect to the anti-ferromagnetism of

the core for smaller particles. Also the nanoparticle at

lower temperatures shows bigger magnetization.

Title: Spatial control of light via harmonic

potential and atomic topological insulators

Name: Yiqi Zhang



Abstract

We investigate spatial control of light, and the

research contains two parts. The first part we focus

on the influence from a harmonic potential [1], and

the second part is about the atomic topological

insulators [2]. The details are:

1. In a fractional Schrödinger equation with a

harmonic potential, we find that the propagation of

one- and two-dimensional input chirped Gaussian

beams is not harmonic. In one dimension, the beam

propagates along a zigzag trajectory in real space,

which corresponds to a modulated anharmonic

oscillation in momentum space. In two dimensions,

the input Gaussian beam evolves into a breathing ring

structure in both real and momentum spaces, which

forms a filamented funnel-like aperiodic structure.

The beams remain localized during propagation.

2. The interference of three coupling fields will

split energy levels periodically, to form a periodic

refractive index structure with honeycomb profile

that can be adjusted by different frequency detunings

and intensities of the coupling fields. This in turn will

affect the appearance of Dirac cones in momentum

space. When the honeycomb lattice sites are helically

ordered along the propagation direction, gaps open at

Dirac points, and one obtains a photonic Floquet

topological insulator (PFTI) in an atomic vapor. Due

to the confinement of edge states, beams will be able

to move along the edge of the PFTI without

scattering energy into the bulk. The formed PFTIs in

atomic ensembles can be easily controlled and

reconfigured by adjusting the frequency detunings,

coupling field intensities, and higher-order nonlinear

susceptibilities.

Title: The research of far-field diffraction and

optical limiting in hot atomic vapor

Name: qian zhang

Affiliation: Institute of Photonics

&Photon-Technology, Northwest University, Xi’an ,

China


Abstract

In this work, we characterize the far-field diffraction

ring patterns in hot atomic vapor cell ( ) by setting the

sample cell at various sample positions. The results

indicated that bright central spots would appear using

a diverging beam and a dark spot would appear using

a convergent beam. An exception for a convergent

beam happened if the sample cell was set close to the

focus point, this phenomenon was well explained by

the Kerr effect together with the thermally induced

optical nonlinearity and simulated by

Fresnel-Kirchhoff diffraction integral formula. In

addition, we found the optimal position of the sample

cell where the lowest limiting threshold and clamp

output are the lowest in the optical limiting.

Title: How to Evaluate the High Power Lasers by

Coherent Beam Combination

Name: yang liu

Affiliation: Wuhan Mechanical Technology College


Abstract

Coherent combination of laser beam is an important


and challenging area of high power laser science, and

how to evaluate the high power laser by coherent

beam combination is a new research spot. Formulas

for the radiated intensity distributions of coherent

combined Gaussian beam array are derived via

Fraunhofer scalar diffraction model by utilizing

representations of the cross-spectral density of the far

field. Effects of beam array numbers and separate

distances etc. on far field radiated profiles are shown

and analyzed. A new conception named power in the

bucket of the main lobe (〖PIB〗_m) is advanced to

measure the beam quality of combined beams. This

evaluation method is useful for efficiently

determining the peak irradiance and power in the

bucket for single emitting apertures of general shape.

Title: Demonstration of Parity–Time Symmetry

in Optically Induced Atomic Lattices

Name: zhaoyang zhang



Abstract

Parity-time (PT) symmetry in optics has been

experimentally demonstrated recently in several

coupled gain-loss solid-state material systems by

purposefully engineering the refractive indices.

Many intriguing and applied features emerge under

such PT-symmetry platform, such as power

oscillations, optical solitons in PT-symmetric lattices,

and nonreciprocal light transmission. Considering

that multi-level atomic gases are quite efficient in

constructing desired refractive index profiles,

schemes based on atomic coherence have been

recently proposed to realize optical potentials

involving PT-symmetric properties. For the first time,

we have experimentally realized optical lattice with

tunable gain-loss waveguides in a

coherently-prepared four-level N-type atomic system.

Particularly, an abrupt phase shift jump has been

clearly observed which indicates the PT-symmetry

breaking by appropriately tuning the pertinent atomic

parameters. The experimental demonstration of such

readily reconfigurable, effectively controllable and

low-cost PT-symmetric periodic structures sets a new

stage in better understanding various properties of PT

symmetry optics and realizing desirable applications.

Title: Study on High-Power Spectral-Flat 2-2.5

μm Supercontinuum Laser Source

Name: Ke Yin

Affiliation: National university of defense

technology


Abstract

2-2.5 μm supercontinuum (SC) laser sources locate at

the infrared atmospheric window, indicat-ing that

there are lots of important atmospheric applications

of these broadband sources. In this paper, a

spectral-flat 2-2.5 μm SC source with optimized

maximum output power of >200 W is re-ported by

adopting a cladding pumped thulium-doped fiber

amplifier. The underlying physical mechanisms


behind the SC generation process are investigated

firstly with a numerical model which includes the

fiber gain and loss, the dispersive and nonlinear

effects. Simulation results show that abundant soliton

pulses are generated in the TDFA, and they are

shifted towards the long wavelength side very

quickly with the nonlinearity of Raman soliton

self-frequency shift (SSFS), and eventually the

Raman SSFS process is halted due to the silica fiber’s

infrared loss. A spectrally-flat 2-2.5 μm SC source

could be generated as the result of the spectral

superposition of these abundant soliton pulses. These

simulation results correspond qualitatively well to

the following experimental results.

The evolutions of the output spectrum and power of

the SC source and temperature of the fiber endcap are

investigated in details. When the repetition rate of the

seed pulses is 2 MHz and 4 MHz, the obtained

maximum output power of the 2-2.5 μm SC laser

source is 157 W and 203.4 W, which corresponds to a

3 dB spectral bandwidth of 550 and 545 nm,

respectively. At the highest output power, the power

spectral intensity is calculated to be as high as 370

mW/nm, which is the bright-est 2-2.5 μm SC laser

source ever reported. The results indicate that by

increasing the repetition rate of the seed pulses, the

SC conversion efficiency of the fiber amplifier could

be scaled together with a less infrared absorption loss

of the long wavelength spectral components.

Meanwhile, the output SC source has a good beam

profile.

This SC laser source, to the best of our knowledge, is

the brightest spectrally-flat 2-2.5 μm light source

ever reported. It will be highly desirable in a lot of

long-range atmospheric applications, such as

broad-spectrum LIDAR, free space communication

and hyper-spectral imaging.

Title: Tuneable, Anomalous Mie Scattering Using

Partial Coherence

Name: Yundou Yang Wang

Affiliation: Northwestern Polytechnical University


Abstract

In 1908, Gustav Mie [1] obtained, on the basis of

Maxwell's equations, a rigorous solution for the

di raction of a plane monochromatic wave by a

homogeneous sphere of any diameter and of any

com-

position situated in a homogeneous medium. After

that, a large number of studies have been devoted

to the question of how the angular distribution of

elds scattered by a sphere can be controlled. This

line of research was initiated by Kerker et al. in 1983

[2]. They derived conditions under which the

forward or backward scattering by magnetic spheres

is strongly suppressed.

Here we show that a J0 Bessel-correlated beam

which is incident on a homogeneous sphere, pro-

duces a highly unusual distribution of the scattered

eld [3{5]. Such beams can be easily generated

using an incoherent annular source [6]. The forward

scattered intensity can be reduced by more than

ve orders of magnitude compared to the case of an

incident eld that is spatially fully coherent.

Strong suppression can also be obtained for the

backward scattered eld by tuning the spatial co-

herence properties of the incident eld. This method

allows the creation of cone-like scattered elds,

with the angle of maximum intensity given by a

simple formula.

Title: Cycle of phase, coherence and polarization

singularities in Young’s three-pinhole experiment

Name: Xiaoyan Pang

Affiliation: Northwestern Polytechnical University


Abstract

The discipline of singular optics, which is concerned

with singularities in the topology of wavefields, has

expanded dramatically over the past decade. It is now

well-established that a variety of singularities can be


characterized and observed. It was originally

concerned with singularities in the phase of scalar

wavefields and not long after, singularities of

polarization were also described. In recent years,

even more classes of singularities have been studied.

Singularities of the spectral degree of coherence

(called correlation vortices or coherence vortices)

have been found in partially coherent scalar

wavefields and eta singularities have been introduced

in partially coherent electromagnetic fields. It is also

known that these phase singularities, polarization

singularities and coherence singularities are

physically related, but the exact nature of their

relationship is still somewhat unclear. We show how

a Young-type three-pinhole interference experiment

can be used to create a continuous cycle of

transformations between classes of singularities,

often accompanied by topological reactions in which

different singularities are created and annihilated.

This ar-rangement serves to clarify the relationships

between the different singularity types, and provides

a simple tool for further exploration.

Abstract

The coupled wave theory for volume holographic

grating with curved interference fringes has been

proposed based on the Kogelnik′s coupled wave

theory with the plane interference fringes. The

formula about the magnitude and directional angle of

grating vector in arbitrary position of volume

holographic grating with curved grating has been

deduced. We found that the wavelength selectivity

and angular selectivity may be different in different

position of volume holographic curved stripe grating

which depend on the angle between the propagation

vector of reference beam and signal beam. The larger

the angle, the greater the angle and wavelength

selectivity, whereas the weaker.

Title: An Implantable, Multi-Functional Neural

Probe based on Printed Microscale

Optoelectronic Devices

Name: Xing Sheng

Affiliation: Tsinghua University


Abstract

Understanding neural structures and functions is

important to resolve the mystery of the complex brain.

Compared to conventional electrophysiological

methods, optical methods have many advantages

since light can be used to stimulate and detect

specific neuronal activities by genetic encoding.

Recent progresses in the design of mechanics and

materials have given birth to flexible and stretchable

electronics and photonics, enabling the integration of

rigid inorganic devices with soft, elastic and curved

biological systems. Here we present an implantable

neural sensing system that integrates high

performance, microscale photonic devices including

LEDs and photodetectors. A blue LED serves as a

light source to excite the genetically encoded calcium

indicator (GECI). A photodetector with a specifically

designed band selective optical coating is used to

probe the GECI fluorescent signal with high

sensitivity. A yellow LED allows us to activate the

chloride pump halorhodopsin, which inhibits local

neural activities. These devices are implanted deeply

into the brain, realizing close loop monitoring and

manipulation of neural activity in vivo. Such an

integrated, deeply implanted and microscale

optoelectronic system provides new insights on

interactions between optical and neural systems.

Title: Bioinspired fabrication of optical fiber SPR

sensors for immunoassays using

polydopamine-accelerated electroless plating

Name: Se Shi

Affiliation: Tianjin University


Abstract

Fabrication of optical fiber surface plasmon

resonance (SPR) sensors has always been a

challenge. It requires some complex and special

rotation devices1,2 in the vacuum evaporation or

sputtering systems, ensuring that the deposition of

gold films on the cylindrical optical fiber surface is

as uniform as possible.

Our group is devoted to the study of the fabrication

and functional modification of the optical fiber SPR

sensors based on the chemical metal deposition and

bioinspired adhesion.3,4 In this report, we will focus

on our recent works in the fabrications of SPR

sensors, especially, the facile, rapid and effective

method for the fabrication of optical fiber SPR

sensors via polydopamine (PDA)-accelerated

electroless plating (ELP)5. Bioinspired PDA coating

was utilized as the versatile material for optic-fiber

functionalization and the gold seeds adsorption of

the ELP (Fig. 1). The fabricated sensors exhibited

higher sensitivity, better reproducibility and

adhesion stability compared with those fabricated by

the traditional ELP. Some key experimental

parameters, including DA polymerization

temperature, DA polymerization time, and plating

time, were investigated in detail. The optimized

samples exhibited high sensitivity ranging from

1391 nm/RIU to 5346 nm/RIU in the refractive

index range of 1.328 to 1.386. Scanning electron

microscopy images indicated that the sensor surface

consisted of gold nanoparticles with a uniform

particle size and an orderly arrangement, and the

film thickness was approximately 60 nm. Another

PDA layer was formed on the gold film for the facile

immobilization of antibodies. The sensor exhibited

effective antibody immobilization ability and high

sensitivity for human IgG detection over a wide

range of concentrations from 0.5 to 40 μg/mL,

which indicate the potential applications of

fabricated sensors in immunoassays.

Abstract

This work describes the implementation and the

modeling of a gas sensor with pulse delta-sigma

architecture. Beyond the conventional technique of

constant periodic heating of light source, our

proposed delta-sigma architecture with closed-loop

feedback system is obtained by the hybrid


combination of a CO2 infrared sensor prototype

which includes an amplifier, ARM based MPU and

discrete electronic devices. After a modeling of

system, we built a model for the description of

re-lationship between gas concentration and sensor

by the duty of heating. The measurement results

show a good linear behavior of signal and prove to

be practical for all the NDIR measuring tech-niques

and this work also gives a new approach not only to

measure gas concentration fast but also obtain the

high resolution.

Abstract

An interferometer based on the subtraction and

addition between wave fields is developed for

determining the surface topography. Four

interference fringe images are recorded by the

proposed interferometer under predetermined

polarization states of signal wave and reference wave

so that the subtraction and addition between waves

are realized. The surface profile is then obtained by

unwrapping the phase map which is generated from

the four images. The error introduced by phase shift

error in the phase shifting interferometer, which is

well-known and widely employed, is avoided.

Title: mRNA of expression of per 1 in mice bone

marrow mesenchymal stem cells irradiated by

red laser

Name: Peng Fei

Affiliation: Renmin Hospital of Wuhan University


Abstract

A core group of circadian genes regulate the

circadian rhythms in mammalian cells. However, the

mammalian cellular circadian rhythm in

photobiomodulation remains unknown. A lot of

evidence has show that >20% of expressed mRNAs

in bone stissues oscillate in a circadian manner. The

aim of this paper is to investigate the mRNA

expression of period 1 (per 1) in murine bone

marrow-derived mesenchymal stem cells (BMSCs)

which were irradiated by 635nm red laser light. The

cells were seeded in 35mm tissue-culture dishes at a

density of 8×104 cells/dish. and cultured in

Dulbecco’s modified Eagle’s medium (DMEM).

BMSCs were irradiated once by 635nm red light with

radiation energies 0J/cm2, 1J/cm2, 4J/cm2. mRNA

expression of per 1 via Semi-Quantitative Real-time

RT-PCR at 0h, 6h, 12h, 18h, 24h. The genes

displayed a oscillatory period of nearly 24 hours.

And 635nm laser light changed the mRNA

expression of per 1. We conclude that red light

irradiation can effect the circadian rhythm of

BMSCs.

Title: The effect of 635nm red laser irradiation


on proliferation of bone marrow stem cells

Name: Peng Fei

Affiliation: Renmin Hospital of Wuhan University


Abstract

Photobiomodulation effects of low-energy light

irradiation on regeneration have been reported in

skin , nerve, and skeletal muscle tissues and bone.

Bone Mesenchymal stem cells (BMSCs) are de-rived

from bone marrow, which exhibited a fibroblast-like

appearance, and could differentiate in vitro into

different lineages. However, there is a a reciprocal

relationship between growth and os-teogenic

differentiation in MSCs. Therefore, it’s important to

investigate the effect of Low-level light irradiation

(LLLI) on BMSCs. The aim of our study was to

investigate the proliferation effect of 638nm red laser

light on bone marrow MSCs with or without

osteogenic supplements. Bone mar-row was

collected from the 4-week-old Sprague–Dawley rats

femur and tibiae. MSCs with and without osteogenic

supplements both were divided into three groups. A

continuous 635nm wave-length red light diode laser

(a power output of 960mW) was used in the study.

The size of light spot was 35mm in diameter.

Irradiation was performed every other day since the

half of medium was changed to osteogenic

differentiation media (ODM). The first irradiation

day was set as 0 day. The duration of each irradiation

for red light was calculated at 10 seconds for 1 J/cm2,

20 seconds for 2 J/cm2. Two of these groups were

used as controls: MSCs incubated in DMEM without

irradiation (control 1), MSCs incubated in ODM

without irradiation (control 2). Cellular proliferation

was evaluated by using WST-8. Cell viability was

assessed with WST-8 kit at 2, 4, 6 and 8 days,

respec-tively. At 4, 6 and 8 days, groups cultured

with DMEM showed significantly higher viabilities

than that in groups with ODM. In groups with

DMEM, red light at all doses significantly stimulated

cell viability as compared with the control 1. Groups

irradiated at 1 and 2 J/cm2 had more effective

pro-liferation on 4 (P＜0.01) and 6 days (P＜0.05),

when compared with the control 1. In groups with

ODM, control 2 and the irradiated groups showed

similar proliferation speeds. In conclusion, we can

find that red light can promote proliferation of MSCs

cultured in normal media, and suppress proliferation

of MSCs cultured in ODM.
