Abstract

We present the results of an investigation of photoinduced anisotropy in films and bulk samples of chalcogenide glasses As₅₀Se₅₀ and Ge₂₀As₂₀S₆₀ using reflectance difference spectroscopy. Anisotropy in a wide spectral range (1.5-5.5 eV) can be generated and reorientated many times by linearly polarized light. We conclude that possibility of orientation and reorientation with the linearly polarized light not only of defects and scattering centers but also of the interatomic covalent bonds is characteristic for different chalcogenide glasses. We have found that doping of a chalcogenide glass Ge₂₀As₂₀S₆₀ by rare earths does not change the parameters and characteristics of photoinduced anisotropy.
