Abstract :
In this work we investigate the fast carrier dynamics in compositionally asymmetrical multiple quantum well traveling wave semiconductor optical amplifier at ultrafast input pulses with different wavelengths. The important role of transport effects in active layers on carrier population recovery after ultrashort pulse propagation is shown.
