Abstract

Two approaches to fabrication of optical nonlinear waveguides consisting of thin glass films doped with CdS_xSe_{1_x} and CdS microcrystallites, deposited onto standard glass substrates are described. The films were fabricated by RF planar magnetron sputtering in Ar atmosphere of two types of targets: a monocomponent one made of CdS_xSe_{1_x} microcrystallites-doped glass and a composite one consisting of an undoped glass plate and CdS powder. The Raman spectroscopy measurements revealed the presence of semiconductor microcrystallites only in the films fabricated with the composite target. Sharp optical cut-off near 500 nm is visible on the transmission spectra of these films. The films can be used as planar optical waveguides. The refractive index of these films at λ= 632.8 nm varies from 1.55 to 1.70 depending on RF power supplied to the sputtering system. Propagation losses for TE_o mode at the same wavelength are about 10 dB/cm.
