Gain calculation of InGaAsP/InP multi-quantum well lasers

Abstract

Anabiical formula for the optical gain based on a sirnpie parabolic-bund by introducing theoretical expressions for the pan tized energy is presented. The model used in this treatment take into account the effects of inlrabmd relmafion. It is shown, as a resuli, that the gain for the TE mode is larger than ihat for TM mode and the presence of accepfor impuriy increase the peak gain.
