Abstract

The longitudinal mode spectrum and the mode suppression ratio of a quantum-well laser are derived in terms of the simulated emission lifetime of the photons in a mode. Analytic expressions are obtained from the Fermi level as a function of current and power as the limiting value of Fermi energy is approached. The model predicts the growth in spontaneous emission as the mirror reflectivity is reduced and predicts mode suppression ratios in good agreement with published values
