| Abstract: | The composition dependence of the refractive index and its photo-induced variation have been calculated for the Ge1?xSex and As1?xSex binary glass systems, using the random network model. It is found that the refractive index has a minimum in Ge1?xSex at x = 0.8, while it shows a monotomic increase with increasing As content in As1?xSex glasses. The refractive index of the Ge1?xSex system decreases with illumination and the variation Δn of GeSe2 is ?0.0316, while the refractive index of the As1?xSex system increases with illumination and the variation of As2Se3 is 0.01. These results are in agreement with the experimental results reported by several workers. |
