RELATION BETWEEN NONLINEAR GAIN AND NONLINEAR REFRACTION IN QUANTUM-WELL SEMICONDUCTOR LASERS
Abstract
The influence of nonlinear gain mechanisms such as carrier heating and spatial and spectral hole burning on the real and imaginary parts of the refractive index is described. The dependence of the total amplitude-phase coupling parameter for nonlinear gain on the laser frequency and pump level is obtained. Carrier heating is shown to be the main nonlinear gain mechanism affecting the above-mentioned parameter.
