【Abstract】 The phenomenon of photoinduced variance of refractive index and thickness in As2S8 amorphous thin films were studied experimentally using ultraviolet light and He-Cd laser. The experimental rules were concluded and also the mechanism analysis was explained. As2S8 glass-base liner waveguide is fabricated using this effect successfully and shows a good wave-guided quality.更多还原
