Abstract

We have performed an experiment in a chalcogenide thin film that is questionning some aspects of the currently accepted phenomenological model for the photoinduced anisotropy in such material. By analyzing the kinetics of the photoinduced linear dichroism, we were able to explain our experimental results by revisiting the current model which is based on anisotropic microstructures. This model is modified to include disk-shaped polarizability tensor. The approach we present is a useful tool to extract information on the optical properties of microscopic structures based on a macroscopic phenomenon.
