摘　　要：实验研究了As_2S_8薄膜光折变现象.提出并采用紫外光激励的方法试制了As_2S_8条形波导,导模激励显示该波导具有良好的导波特性.在此基础上,考察了As_2S_8条波导的光阻断效应,实现了光-光效应的开关功能.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.
