Notes:
A significant increase in storage time by thermal fixing of photorefractive (PR) gratings in a polymeric composite of poly-9-vinycarbazole, tricresyl phosphate, fullerene, and 4-N,N-diethylamino-β-nitrostyrene is demonstrated. The fixing of the volume holograms is created by quasifreezing the orientation of the linearly anisotropic chromophore molecules. The fixed PR gratings can be easily erased by elevating the sample's temperature to the glass transition temperature of the composite. The readout of the thermally fixed first-order grating does not require the presence of an external electric field. © 1997 American Institute of Physics.
