The photorefractive phenomenon of As2S8 film is reported in this paper. An ultraviolet irradiation technique is presented and applied successfully to As2S8 channel waveguide preparation on the basis of analyzing these experimental data. This channel waveguide of As2S8 displays good characteristics of a waveguide using a guided mode excitation. It is found that the optical stopping effect of As2S8 channel waveguide has the rotential application owing to its switching function with the photo-optical effect.
