Optimizing the Performance of Single-Mode Laser Diode System Using Genetic Algorithm

Abstract

In this correspondence, micro-genetic algorithm (MGA) application results for optimizing the performance of electronic feedback of a laser diode are presented. The goal of optimization is to find the maximum bandwidth of the laser diode with electronic feedback used in fiber optic digital communication. A numerical analysis of the system theory of the single-mode laser diode to obtain numerical results of the gain, the Pulse response, and the harmonic distortion for electronic feedback is also presented. The dependence of the system gain on the feedback gain and delay is examined. The Pulse response is studied and it is shown that a transmission rate over 1 Gbyte/s can be achieved.
