Abstract
A purely electronic model of photoinduced optical anisotropy in glassy semi conductors is formulated. The model is based on the concept of geminate ele ctron-hole pairs captured by correlated deep traps. The kinetics of photoin duced anisotropy are controlled by the photogeneration, trapping and recomb ination of geminate pairs. Predictions of the model are shown to be in agre ement with experimentally observed basic characteristic features of photoin duced anisotropy.
