Record high saturation output power (+20 dBm) and low NF (6.0 dB) polarisation-insensitive MQW-SOA module

A polarisation-insensitive semiconductor optical amplifier module with a thin tensile-strained multiple quantum well active layer is developed. The module exhibited a record high saturation output power of +20.0 dBm and a low noise figure of 6.0 dB at 1550 nm together with a small polarisation-dependent gain of 0.6 dB.
