Photopolymer-Filled Nanoporous Glass as a Dimensionally Stable Holographic Storage Medium

Plane-wave holograms were angle-multiplexed in a photopolymer-filled nanoporous glass system. The angular selectivity curves of the multiplexed holograms were in agreement with predictions from Kogelnik's coupled wave theory of volume phase holograms. The recorded holograms also exhibited nearly negligible Bragg detuning. This system exhibits the high dimensional stability that is required of media for many applications of volume holography.
