Abstract
Optical storage caused by photo-induced anisotropy in yl-4'-bis(N,N-ox yethylene)imino-4-nitro-azobenzene sebacoyl] film is studied by degene rate four-wave mixing. Molecule orientation gratings which are stable for three months are produced. The grating in the sample can be ''eras ed'' by using circular polarized light. So an azobenzene polymer thin film can be used many times to restore optical information.
