Abstract

Optical nonlinear properties of the waveguiding structures consisting of thin films of Corning 7059 glass deposited by rf magnetron sputtering onto Cd(S,Se)-doped glass substrates (Schott long-pass filters) have been studied utilizing the effect of power-dependent prism coupling. The experiments were performed at a wavelength of 0.4880 μm with an argon-ion laser working in both cw and mode-locked (1-ns pulse duration) regimes. In’ both cases a limiting action in prism coupling was observed. Moreover hysteresis (output vs input light intensity) was observed with a pulse illumination. The changes in mode coupling angles with the variation of the input intensity were measured and the data obtained were utilized to determine both the sign and the value of the nonlinearity. We have also performed introductory studies on the technology of waveguides fabricated by sputtering of Cd(S,Se)-doped glasses onto optical linear glass substrates. The most recent progress in our research is presented.
