Abstract

In this study, different second harmonic distortion (2HD) levels of a 1.55 micrometers , InGaAsP ridge waveguide laser diode are investigated by using a mathematical model based on multi-mode rate equations. The rate equations with an input current i are solved numerically by using fourth order Runge-Kutta algorithm for frequencies ranging from 1 GHz to 10 GHz with 1 GHz steps and the standard parameter values. The important parameters of 1.55 micrometers . InGaAsP semiconductor lasers such as Auger recombination, non- radiative recombination, spontaneous emission lifetime and gain saturation are taken into account. The effects of some parameters on 2HD for different threshold levels are examined and computed graphically.
