Abstract
Semiconducting chalcogenide glasses become optically anisotropic solid s with the optical axis parallel to the direction of the inducing ligh t beam after exposure to unpolarized light. This photoinduced anisotro py (PA) can be detected in bulk samples by means of a probing beam dir ected perpendicularly to an unpolarized inducing beam. In chalcogenide films, PA induced by an unpolarized glancing-angle beam can be detect ed by means of a probing beam that is incident normal to the films.
