Abstract
We present a theoretical analysis of some new properties of TE waves in waveguides consisting of an optical linear thin film deposited onto the surface of a substrate exhibiting both positive and negative nonlinearities at two different wavelengths. The semi-infinite substrate is characterized by an intensity dependent refractive index ns= nso+ n2S, where S is the local power density and n2 is the nonlinear coefficient. The data set used in our calculations concerns a particular structure consisting of a film of Corning 7059 glass deposited onto the surface of a Schott GG 495 glass filter. Color filters made with glasses doped with crystallites of the mixed semiconductor CdSxSel_x exhibit third order nonlinearity with n2 of about 10-14m2/W. It is also known1 that the sign of the nonlinearity in these glasses changes in the vicinity of a band gap. The material parameters for positive nonlinearity at λ = 0.4765 pm and negative nonlinearity at λ= 0.4880 mm are the following: Corning glass film refractive indices nf= 1.597 and 1.595; substrate refractive indices nse 1.573 and 1.569; imaginary parts of dielectric constant of the substrate c" = 2.8 x 10 and 6.5 x 10-5 respectively.
