Abstract
In many respects, the intrinsic response parameters of photorefractive (PR) polymers are rapidly becoming comparable to those of inorganic crystals.1 Therefore, these materials are beginning to be considered for practical device applications, including holographic optical data storage. Since both the diffraction efficiency of a photorefractive material and the Bragg selectivity (which controls the number of patterns which can be multiplexed in a material) increase with thickness, samples on the order of 1-cm thick will probably be necessary for eventual device applications.
