Abstract

Four new types of highly efficient amorphous azobenzene polymers for reversible holographic storage were synthesized. Two photoinduced effects contribute to their high efficiency: linear birefringence and surface relief. Using polarization holography, these two effects were separated and their time evolution was observed simultaneously. The results show that the mechanism of the appearance of the linear birefringence and the surface relief and their erasure with circularly polarized light beam are different.
