Abstract :
Summary form only given. Carrier transport, capture and escape processes in multiple quantum well (MQW) lasers have been shown to affect the high speed and static characteristics of the device. Recently, we have demonstrated that these processes also significantly affect the bias-dependent carrier lifetime, and consequently the recombination parameters that are extracted from this lifetime. In this work we investigate carrier transport processes in InAsP-InGaAsP MQW lasers from the transient response of the photoexcited emission created under conditions of high excitation.
