Hybrid polarization-angle multiplexing for volume holography in gold nanoparticle-doped photopolymer

We report on volume holographic hybrid polarization-angle multiplexing in a gold nanoparticle-doped photopolymer. When doping the gold nanoparticles, the linear photoinduced birefringence of the phenanthrenequinone-doped poly (methyl methacrylate) (PQ/PMMA) photopolymer could be increased by nearly 38%. The data pages could be recorded with the orthogonal circular polarization multiplexing, and the reconstructed images have a symbol-error rate of 3.81% and 4.46% for left circular polarization and right circular polarization state, respectively. Two biological image sets multiplexed both with the angle interval of 0.1° and with orthogonal circular polarization are reconstructed separately and simultaneously.
