Celebrating the EDFA, (Erbium Doped Fibre Amplifier)


It was a discovery that was set to transform the Internet and become the backbone of the World Wide Web as we know it today.

Now, a quarter of a century later his development of the erbium doped fibre amplifier (EDFA) – the world’s first successful optical amplifier, which employs the rare earth ion erbium to boost the intensity of the signals as they propagate through the world wide web of optical fibres- still plays a pivotal role in our global communications.

“In the early 1980s there was no known electronic device capable of regenerating signal data at hundreds or thousands of gigabits per second over large global distances,” said Sir David, who was recently awarded a knighthood in the Queen’s New Year’s Honours List for his services to photonics, the science and application of light and electronics.

But in 1987, Sir David and his team at the University of Southampton made a technological breakthrough using a special fabrication process to very lightly dope the core of optical fibres with the rare-earth element erbium and pump the atoms with an auxiliary laser. This created EDFAs that could boost the intensity of signals allowing them to travel through the global web of optical fibres that we have today.

It was a unique invention that was a major factor in the rapid development of the fibre-optic networks in the 1990s, overcoming the problem of transmitting data over large distances and extending the gap between costly regenerators.

It fuelled an explosive growth in the Internet due to the ability of EDFAs to transmit and amplify huge amounts of data and was widely regarded as one of the foremost developments in contemporary communications. More than one billion Internet users now exchange over 2,000 Petabytes of data every month, the vast majority of which passes through EDFAs.

Recalling his development of these life-changing EDFAs, Sir David said: “When we developed the EDFA in 1987 we underestimated the enormity of its impact on telecommunications.

“It has made possible the explosive growth in the Internet through its ability to transmit and amplify vast amounts of data. Our lives today would be unimaginable without it. I am proud to see its benefits 25 years on.”

Nowadays virtually every optical fibre is amplified with EDFAs, allowing oceans and continents to be spanned. They are also vital components in many of our everyday services from mobile phones to ATM cash machines.

But the potential future use for EDFAs is still being explored. Rare earth-doped fibres can be used to make fibre lasers which are revolutionising manufacturing, especially high-speed metal cutting, welding and marking, as well as in possible future security applications.

Since the invention of the laser, an important and growing application of rare earth ions has been as an active medium for light generation. Most rare earth ions provide fluorescence; when excited with a light source

they emit at characteristic wavelengths according to their electronic energy levels and the properties of the host material. Among the fifteen rare earth elements, there are hundreds of possible emission bands from UV wavelengths to infrared.

Like the erbium-doped fibre amplifier, rare earth doped fibres can also be used to make fibre lasers. Today’s optical fibre lasers can generate kilowatts of power from a single hair-thin thread of ytterbium-doped glass and are revolutionising manufacturing, especially high-speed metal cutting. They are replacing inefficient and bulky CO2 lasers with compact and efficient solid state devices that offer stable beam quality. Optical fibre-related products are not only penetrating existing markets but, more significantly, they expand the application into areas that are impossible by conventional technologies.

Twenty five years ago Sir David Payne, Director of the University of Southampton’s Optoelectronics Research Centre (ORC) and his team made one of the most significant developments of modern telecommunications.


David is being recognised for his extensive contributions to harnessing light in telecommunications, sensing, and lasers for manufacturing. He has to his credit an astonishing number of key discoveries, including his pioneering research developing the world’s first practical optical fibre amplifier – the Erbium-Doped Fibre Amplifier (EDFA) – and its use in optical fibre transmission systems (see page 4). This crucial component forms the backbone of the Internet and made possible its explosive growth through an ability to transmit and amplify vast amounts of data.

The EDFA, developed in 1987, is widely regarded as one of the most significant developments in modern telecommunications. Every time you use the Internet, your mobile phone or an ATM you are using technology developed at Southampton.

David, who is among the most highly honoured UK scientists, says:

“I was recently described by my peers as the man who made phone calls free. While this is an exaggeration, it conveys the profound impact of the optical internet on our daily lives. Thousands of engineers and scientists

worked away in the background and changed our world for the better. When some of us are recognised publically for what we have achieved, it is a wonderful accolade for us all.”

An international researcher who has spent his entire career spanning five decades with the University, David is one of the most highly recognised scientists in the UK, as evidenced by numerous international honours and awards. He has made many influential discoveries in diverse areas of photonics, from telecommunications and optical sensors to nanophotonics and optical materials.

His pioneering work in fibre fabrication in the 1970s resulted in most of the special fibres used today. He also led the team that developed the single mode silica fibre laser and broke the kilowatt barrier for the output power. Some of the highest power fibre lasers in the world have been designed by David and his team.

Fibres invented and made in Southampton are on the Moon and Mars, while David’s ideas navigate airliners, cut steel, mark smart phones, manufacture life-saving medical devices, help defend our nation and power the Internet.

As a leading University entrepreneur, David’s activities have led to a photonics cluster of 10 companies surrounding the ORC, creating jobs and wealth in the Southampton region. With colleagues, he founded SPI Lasers plc, a leading supplier of high power fibre lasers located in Hedge End, Hampshire.

University of Southampton Vice-Chancellor Professor Don Nutbeam comments: “The erbium-doped fibre amplifier is a crucial invention that has made possible the global information superhighway and high-speed telecommunication networks, which are so important to us all in the 21st century. I am delighted that the unique contribution David has made through his research is being recognised with this prestigious honour.”

“I am delighted that David has been honoured in this way,” adds Professor Dame Wendy Hall, Dean of Physical and Applied Science at the University of Southampton. “He richly deserves it for his personal achievements but it is also an honour for the University of Southampton, which has been his home as both a student and a professor for nearly 50 years.”

Professor David Payne receives Knighthood in the Queen’s New Year’s Honours ListProfessor David Payne, Director of the Optoelectronics Research Centre (ORC) at the University of Southampton, has been knighted in the Queen’s New Year’s Honours List for services to photonics, the science and application of light and electronics.

Super silica. Developing the strongest, lightest glass nanofibres in the world

The University of Southampton’s Optoelectronics Research Centre (ORC) is pioneering research into developing the strongest silica nanofibres in the world.

“Our discovery could change the future of composites and high strength materials across the world and have a huge impact on the marine, aviation and security industries. We want to investigate their potential use in composites and we envisage that this material could be used extensively in the manufacture of products such as aircraft, speedboats and helicopters”

Gilberto Brambilla Principal Research Fellow


Globally the quest has been on to find ultrahigh strength composites, leading ORC scientists to investigate light, ultrahigh strength nanowires that are not compromised by defects. Historically, carbon nanotubes were the strongest material available, but high strengths could only be measured in very short samples just a few microns long, providing little practical value.

Now research by ORC Principal Research Fellow Gilberto Brambilla and ORC Director Professor David Payne has resulted in the creation of the strongest, lightest weight silica nanofibres – ‘nanowires’ that are 15 times stronger than steel and can be manufactured in lengths potentially of 1000’s of kilometres.

Their findings are already generating extensive interest from many companies around the world and could be set to transform the aviation, marine and safety industries. Tests are currently being carried out globally into the potential future applications for the nanowires.

“With synthetic fibres it is important to have high strength, achieved by production of fibre with extremely low defect rates, and low weight,” said Gilberto.

“Usually if you increase the strength of a fibre you have to increase its diameter and thus

its weight, but our research has shown that as you decrease the size of silica nanofibres their strength increases, yet they still remain very lightweight. We are the only people who currently have optimised the strength of these fibres.

David explained: “Weight for weight, silica nanowires are 15 times stronger than high strength steel and 10 times stronger than conventional GRP (Glass Reinforced Plastic). We can decrease the amount of material used thereby reducing the weight of the object.

“Silica and oxygen, required to produce nanowires, are the two most common elements on the earth’s crust, making it sustainable and cheap to exploit. Furthermore, we can produce silica nanofibres by the tonne, just as we currently do for the optical fibres that power the internet.”

The research findings came about following five years of investigations by Gilberto and David using Gilberto’s £500,000 Fellowship funding from the Royal Society.

Gilberto shared his findings with fellow researchers at a special seminar he organised in November 2012 at the Kavli Royal Society International Centre, at Chicheley Hall, in Buckinghamshire.

“It was particularly challenging dealing with fibres that were so small. They are nearly 1,000 times smaller than a human hair and I was handling them with my bare hands,” said Gilberto.

“It took me some time to get used to it, but using the state-of-the-art facilities at the ORC I was able to discover that silica nanofibres become stronger the smaller they get. In fact when they become very, very small they behave in a completely different way. They stop being fragile and don’t break like glass but instead become ductile and break like plastic. This means they can be strained a lot.

“Up until now most of our research has been into the science of nanowires but in the future we are particularly interested in investigating the technology and applications of these fibres,” said Gilberto.

The CAN concept (figure 1) shows how the output of a single fibre laser is split into many channels, and amplified to produce many identical high energy pulses. These pulses are coherently summed together to produce a single pulse whose energy is comparable with the pulses available from conventional very high energy pulsed lasers, but unlike conventional systems this laser can produce thousands of pulses per second instead of one or two.

Laser particle acceleration is a new and potentially revolutionary technology, but is affected by two main issues: efficiency and repetition rates. The lasers used at present consume too much power, and can only produce the required ultrafast laser pulses around once per second to produce acceleration. For many applications needing high repetition rates – particle acceleration, X-ray and gamma ray generation – this makes the use of lasers economically unacceptable and impairs the spread of important scientific and societal laser applications in science, material science, environment, medicine and energy.

However, using fibre lasers may resolve this issue. Fibre lasers can operate at very high average powers, because of their ability to manage the heat generated by laser action. This allows the laser to produce pulses many thousands of times per second, allowing particle acceleration at high repetition rates necessary for real-world applications. Fibres should also improve the overall power efficiency of suitable lasers by a factor of a thousand, making them more economically feasible for experiments.

Ultrafast fibre lasers, however, can produce only lower energy pulses because of optical nonlinearities in the fibre medium, so don’t have the requirement for high energy physics.

The International Coherent Amplification Network (ICAN), a new EU-funded project, aims to harness the efficiency, controllability, and high average power capability of fibre lasers to produce high energy, high repetition rate pulse sources. This will be achieved through a novel laser system, which combines the output of thousands of pulsed fibre lasers.

Dr Bill Brocklesby from the ORC, project manager of ICAN, says: “High-energy ultrafast lasers have already been demonstrated but the challenge to produce high-energy ultrafast pulses at high rates is a specialty for the ORC. Our track record in the development and fabrication of new optical fibres is unparalleled.”

The ICAN project, which will last 18 months, has four main laboratories involved – The Optoelectronics Research Centre (ORC) at the University of Southampton; Ecole Polytechnique, Paris; The Fraunhofer Institute for Applied Optics and Precision

Engineering (Fraunhofer IOF); and CERN, the European Organisation for Nuclear Research and home to the LHC, the world’s largest and highest-energy particle accelerator. It also involves a large number of worldwide partners from the laser, fibre and high-energy physics communities and industry.

Using fibre lasers for ground-breaking particle acceleration technologies

Scientists from the Optoelectronics Research Centre (ORC) at the University of Southampton are part of an international project that is investigating the use of fibre lasers in ground-breaking particle accelerator technologies, such as the Large Hadron Collider (LHC).

Figure 1


Southampton’s award of £3.2 million - the country’s 5th highest award amongst 31 successful institutions - was announced by Business Secretary Vince Cable during Global Entrepreneurship Week.

The funding comes from the Engineering and Physical Sciences Research Council (EPSRC), the UK’s leading funding agency for engineering and physical sciences research, to create ‘Impact Acceleration Accounts’. These Accounts will support the very early stage of turning research outputs into a commercial proposition – the gap between a research idea and developing it to a stage where a company or venture capitalist might be interested.

The Accounts will also allow universities to fund secondments for scientists and engineers to spend time in a business environment or for industrial partners to directly access leading edge research relevant to their business needs. In this way, the account will help stimulate the economy by

EPSRC funding boost for science innovation

The University of Southampton has been awarded part of a £60m investment in UK universities to help the most pioneering scientists and engineers create successful businesses from their research, improve industrial collaboration, and foster greater entrepreneurship.


helping companies become more innovative and provide them with a competitive advantage. This will also better equip our next generation of researchers by improving their knowledge, skills and understanding of the way companies operate and the challenges they face.

The Business Secretary said: “The UK’s scientists are some of the most innovative and creative people in the world, but they need support to take their best ideas through to market. This investment will help our leading universities become centres of innovation and entrepreneurship, generating commercial success to fuel growth.”

Professor Sir David Payne, Director of the Optoelectronics Research Centre at the University welcomed the funding, saying:

“It is great to see EPSRC taking a lead in innovation, the alchemy that turns ideas into wealth. The ORC has a long history of innovation and we have the battle scars to

prove it, as well as a number of successful photonics companies in the local area who owe their origins to the ORC. This new funding will greatly ease the mobility of scientists and engineers between commerce and university research labs. That can only be a good thing.”

The main activities to be supported by the Southampton Impact Acceleration Account will be flexible secondments to the University and into regional businesses; internships for postgraduate research students to work in local start-up companies and the development of technology to market readiness. Not only will these activities benefit the commercialisation of University research, they will directly support small-to-medium sized enterprises (SME’s) like Covesion, one of 10 innovative photonics companies which successfully spun out of research from the University’s Optoelectronics Research Centre.

Industry secondments from the University to Covesion have helped to accelerate the commercial development of the company’s revolutionary laser crystal technology. Over the last three years, Covesion has benefitted from access to facilities and intellectual expertise brought directly into the company to quickly bring their ground-breaking developments to new global markets.

Mark Middleton, CEO of Covesion Ltd, commented, “Via the various knowledge transfer schemes Covesion has in place with the University of Southampton, Covesion has been able to create a product portfolio supporting many growth markets and emerging opportunities. Access to the ORC’s world-leading clean-room facilities and expertise has put Covesion at the forefront of our technology, developing a commercial base of over 350 companies world-wide with revenues doubling year-on-year.”
