Abstract

In this paper, we investigated the diffraction efficiency of polarization holography using by amorphous Ag/As$\sub$40/Ge$\sub$10/Se$\sub$15/S$\sub$35/ multi-layer thin films by He-Ne laser. Multi-layer structures were formed by alternating a layer of metal(Ag) and chalcogenide(As$\sub$40/Ge$\sub$10/Se$\sub$15/S$\sub$35/). The holographic grating in these thin films has been formed using a lineally polarized He-Ne laser light (633nm). The diffraction efficiency was investigated the two sample of Ag/As$\sub$40/Ge$\sub$10/Se$\sub$15/S$\sub$35/-7 layers and Ag/As$\sub$40/Ge$\sub$10/Se$\sub$15/S$\sub$35/-15 layers. As the results, we found that the diffraction efficiency of Ag/As$\sub$40/Ge$\sub$10/Se$\sub$15/S$\sub$35/-7 layers and Ag/As$\sub$40/Ge$\sub$10/Se$\sub$15/S$\sub$35/-15 layers were 1.7% and 2.5% respectively
