Abstract

Numerical results for carrier and radiation confinement in a Distributed Feedback (DFB) Multiple Quantum Well Laser (MQW) are presented. The energy eigenvalues for electrons and holes are calculated by solving the one dimensional time-independent Schrodinger equation and the TE confined modes are found by exploring the analogy between particle and electromagnetic wave equations. The optical gain is obtained for different injection levels by using the Fermi golden rule. Regarding the longitudinal aspects, the threshold gain is obtained as a function of the detuning by using the coupled wave theory which takes into account the parameters defining the corrugation and the cavity terminations
