Numerical analysis for the static and dynamic responses of an HPT/QW-LD optoelectronic integrated device

摘要

Several functions such as optical amplification, switching, and bistability can be obtained by monolithic integration of optoelectronic devices. A physical model for the operation of an optoelectronic integrated device (OEID) composed of a heterojunction phototransistor (HPT) monolithically integrated over a quantum level laser diode (QW-LD) is developed to investigate quantitatively dynamic and static responses of the QW-OEID. We have considered the internal optical feedback and its effect on the frequency response of the device. The results of the numerical analysis for the dynamic and static responses and their dependency on the device parameters are presented.
