Acceleration of Carrier Lifetime in Gain-Clamped Semiconductor Optical Amplifiers

IEEE Photonics Journal, 2018
A new method to accelerate the carrier lifetime in semiconductor optical amplifiers (SOAs) is experimentally demonstrated. The four-wave mixing (FWM) effect is induced without recourse to external optical light sources.
