Simulation of a Double Ridge Edge Emitting InGaAsP/InP MQW Laser

Introduction

In order to investigate the influence of ridge separation on the transverse optical modes of a double ridge edge multiple quantum well (MQW) emitting laser, we have designed a generic device based on the InGaAsP/InP MQW 1.5µm wavelength emission. The aim of this study is to investigate power loading in the structure with increasing bias using the bottom layer as the reference plane.

To do this, the first three transverse modes were considered and the power associated with each mode was monitored as a function of the device design. Silvaco ATLAS LASER was used for this investigation.
