Abstract

Effect of light irradiation on evaporated chalcogenide glass films of an As-Se-S-Ge system has been studied. Utiling this characteristics diffraction grating of the amorphous film was obtained. Parameters such as film thickness, composition, and exporsure time influencing the diffraction efficiency were also studied. The maximum value of the diffraction efficiency achieved was 4.6% in an $As_{75}Se_{15}S_{35}-Ge_{10}$ film.
