Abstract
Color glass filters doped with small semiconductor (CdSxSe1−x) crystallites have been shown1 to have very large third-order susceptibilities (n2 ≃ 10−13−10−14 m2/W). They are potentially very useful for a variety of all-optical signal processing operations, such as testability, optical logic, or degenerate four-wave mixing, providing that the relaxation time of the nonlinearity is sufficiently fast. An upper limit of 1 nsec has been reported for the carrier lifetimes by Jain and Lind.1
