Uncooled, polarization-insensitive AlGalnAs MQW-SOA module operable up to 75°C with constant current

A world's first uncooled, polarization-insensitive 1.3-μm SOA module was developed using an AlGaInAs MQW-SOA. A very small gain variance of 3.8 dB including PDG was demonstrated over a wide temperature range from 25 to 75°C at a constant current.
