Abstract

The effect of coupling between quantum wells on the gain spectra, and on the differential gain is investigated assuming that the optical gain possess multiple peaks. The gain spectra showed many peaks located at the heavy-hole and light-hole transitions. Therefore, the lasers under investigation are being treated as multiple-level systems. It is shown that the dependence of these peaks is a function of the barrier thickness. Computer generated plots illustrate the use of analytic expressions for finding eigenvalues of the Schrodinger equation. Results and discussion for the gain spectra and for the differential gain are explained as bearing a relation to the bound-state energy eigenvalues. Such parameters of a GaInAsP-InP double quantum well laser are presented as a specific example.
