Nonlinear optical properties of thin-film waveguides deposited onto semiconductor-doped glasses

Abstract
We report the fabrication procedure and properties of optical nonlinear guided wave structures consisting of a thin film of Corning 7059 glass deposited on the surface of CdSxSe1−x doped glass. The limiting action in power-dependent prism coupling in the structures produced is described. The nonlinear prism coupling is used to evaluate both the sign and the steady-state value of the intensity-dependent refractive index of the substrate. For the glass used the nonlinearity is negative and its value is in the range of 10−10 m2/W.
