Abstract
Highly nondegenerate four-wave mixing processes in bulk semiconductor optical amplifiers are analyzed by comparing experimental data at detu ning frequencies up to 3 THz with numerical calculations based on semi classical density-matrix equations. Carrier heating and spectral holeb urning are found to be dominant in mediating wave mixing in the THz re gion and lead to comparable contributions to nonlinear gain suppressio n in semiconductor lasers.
