Abstract

Semiconductor-doped glasses, incorporating small CdS_xSe_1–x or CdSe_xTe_1–x crystallites in a glass matrix, show strong nonlinear absorption¹ and large values of the nonlinear optical susceptibility χ₈ have been reported in recent degenerate-four-wave-mixing experiments². This nonlinearity has been attributed to the generation of a dense electron-hole plasma in the semiconductor crystallites.
