D7. Analysis of Dynamic Characteristics of InAs/InP (113) B Self-Assembled Quantum Dot Lasers Using Multi- Population Rate Equations MPRE Model

Multi population rate equations model is used to analyze the dynamic characteristics of the InAs/lnP (113) B quantum dot laser. In which, We have solved the rate equations for InAs/lnP (113) B self-assembled quantumdot laser considering homogeneous and inhomogeneous broadening of optical gain numerically using fourth-order Runge-Kutta method. The steady state value and tum-on delay improve as injection current increases. With decreasing the full width at half maximum (FWH M) of homogeneous broadening, tum-on delay decrease and the laser reaches its steady state faster due to enhancing of central group carriers. Finally, this paper studies the effect of the initial carrier relaxation which corresponds to phonon bottleneck.
