title: Optical nonlinearities in semiconductor-doped glasses.
abstract: We present a phenomenological theory of the intensity-dependent dielectric function of semiconductor-doped glasses near the absorption edge. It is shown that efficient phase conjugation by degenerate four-wave mixing should be possible in these materials.
