Abstract

Multi Populations Rate Equations (MPREs) model is used to analyze the dynamic characteristics of the InAs/InP (113) B self assembled quantum dot laser. The resulting system of differentaial equations is solved using fourth-order Runge-Kutta method taking into consideration homogeneous and inhomogeneous broadening of optical gain. The effects of the injected current, Full Width at Half Maximum (FWHM) of the homogenous broadening, and initial relaxation time (phonon bottleneck) on the rise time, fall time, and hence the maximum allowable bit rate of the optical signal are investigated.
