Abstract :
The two-photon photochemistry described here is a potential candidate for 2-d spatial multiplexing in volume holographic storage. The initial diffraction efficiency obtained in these materials is promising. Issues remain with understanding and avoiding the decay of the initial diffraction efficiency, and with reducing the absorption of the exciting wavelength without simultaneously reducing the diffraction efficiency. The ease of manufacture of the two-photon photochemical system compared with the inorganic photorefractives makes them attractive for the holographic storage application
