Abstract

In this work a complete simulation of single quantum well (QW) blue–green injection lasers was performed using conventional electron-hole plasma theory for the optical gain in strained quantum well lasers and classical one-dimensional transport in semiconductor heterostructures. The physical model is based on the self-consistent solution of the Poisson’s equation, the current continuity equations, including the thermionic emission theory for carrier transport across heterojunctions,¹ the photon rate equation² and the scalar wave equation for the optical field.³ The band structure of the strained ZnCd_0.2Se_0.8/ ZnS_0.06Se_0.94 QW was calculated using k.p theory.⁴
