Performance Optimization of Multi-Quantum Wells Laser Used in Optical Communications

Abstract

In this work, an analytical treatment of some design parameters of multiquantum well semiconductor laser aiming to optimize the performance of such systems is presented. The treatment concentrates on three main parameters; the reflectivity of the front mirror, the effective lifetime of the photon inside laser cavity, and the number of quantum wells in the laser structure. These three parameters relate to several other parameters which impose to achieve design compensation. Such compensation can be simulated by analytical treatments because the characteristics of these lasers have been established well in form of small and large signal solutions. These lasers are increasingly studied due to their characteristic features in optical communications architectures, low-dimensioned photonics and optoelectronics devices.
