Acrylamide-based photopolymer for microholographic data storage

The application of an acrylamide-based holographic photopolymer for bit-format holographic data storage is investigated. Holographic reflection gratings with a spatial frequency of 5640 lines/mm and micrometer radius were recorded at 532 nm wavelength using 1 μJ write energy. A diffraction efficiency of up to 0.2% was measured.
