Abstract
A microscopic model of the gain and refractive index change in multi-quantum well lasers is applied to study the linewidth enhancement factor. The following issues in the model are studied: the lineshape used to broaden the gain, band gap renormalization, self consistent band bending and carrier spill out into the separate confinement layers. The application of the model to laser design issues is illustrated through consideration of the influence of well strain and barrier band gap. Comparison is made to experiment.
