| Abstract: | The photoinduced phenomena of As_2S_8 film under an ultraviolet and He-Cd laser irradiation are reported.It is confirmed that the refractive index of As_2S_8 film increases,the volume of As_2S_8 film decreases,and the visible optical absorption spectra edge of As_2S_8 film is shifted to the short wavelength after light irradiation.Based on study of these phenomena,an As_2S_8 channel waveguide was fabricated successfully by applying the photorefractive effect.On study of the optical stopping effect of As_2S_8 channel waveguide,it was found that the application of this effect possesses a useful switching function with the photo-optical effect. |
| Keywords: | guided wave optics amorphous As_2S_8 semiconductor films photoinduced phenomena optical stopping effect |
