Third-order nonlinearities in Ge/sub 33/As/sub 12/Se/sub 55/ glass for high-index contrast fiber devices

The nonlinear properties of a chalcogenide glass, Ge/sub 33/As/sub 12/Se/sub 55/, were investigated. This glass shows promise for fabrication into high-index contrast highly nonlinear fiber because of its relatively high glass transition temperature and nonlinear index of refraction.
