Paper Abstract

The linewidth enhancement factor, (alpha) , plays a key role in our ability to obtain spatially coherent output from high-power semiconductor lasers and amplifiers. To obtain (alpha) values, modal gain and carrier-induced refractive index change have been measured in broad-area quantum well epitaxial structures with various well depths, widths, and compositions as functions of current density.
