    "abstract": "Peculiar light-matter interactions can break the rule that a single beam\npolarization can address only two states in an optical memory device.\nMultistate storage of a single beam polarization is achieved using self-induced\nsurface diffraction gratings in a photo-active polymer material. The grating\norientation follows the incident light beam polarization direction. The\npermanent self-induced surface relief grating can be readout in real time using\nthe same laser beam.",
