Abstract

Optical materials with fast response times and large nonlinear susceptibilities are central to optical domain computing devices. Though semiconductor doped glasses have a fast response time, in the picosecond range, their moderate magnitude of susceptibility requires a high laser power density to make them usable. Theoretical calculations have shown that a large enhancement of the intrinsic susceptibility in these glasses could be achieved by the fabrication of structured nanoparticles.^1,2 The purpose of this work is to fabricate metal-coated nanoparticles, with nonlinear cores, in a glass host. The current emphasis of this effort is on silver as the metallic component and the semiconductor CdSSe or CuCl as the nonlinear core.
