Abstract :
Extremely large electron-LO phonon intrasubband scattering time (8 ps) was obtained, by the rate-equation analysis for the experimental time-development of the carrier temperature in a 1.5 μm-band multi-quantum-well (MQW) laser amplifier. Consequently, pronounced optical output power saturation was predicted in the MQW laser
