PRELIMINARY INFORMATION | R-SOA-EAM-1550

Description The R-SOA-EAM-1550 is a reflective optical device that provides optical gain and high-speed optical modulation in a single monolithically integrated InP chip. The device uses an advanced MQW semicon-ductor structure to achieve high performance and low power requirements. Typical SOA bias currents are =100mA and the EAM is operated at a reverse bias up to –3V with ~3Vpp RF drive voltage. It has a fibre with an Angled Polished Connector (APC).

R-SOA-EAM-1550 —Semiconductor Optical Amplifier (SOA) and Reflective Electroabsorption Modulator (REAM) at 1.55µm

Features • 1.55µm C-band operation • High performance SOA

• Low polarisation sensitivity (~0.5dB) • >15dB optical gain on chip • Optical mode converter for low loss • Low coupling loss to optical fibre (<1dB) • Low reflectivity facet (R <10-5) • Low drive current for SOA (<100mA)

• High performance REAM • 18GHz EO bandwidth • 9dB dynamic ER • Low chirp • 10Gb/s long reach, 80km transmission over SMF • 20Gb/s modulation capabilities

Application Examples • Colourless transmitters • WDM-PON, 10G EPON • Metro networks • Long reach high speed Access • High-speed optical interconnects • Optical sensors/transmitters
