Phenanthrenequinone-doped poly(methyl methacrylate) photopolymer bulk for volume holographic data storage

We present the design and fabrication of a phenanthrenequinone-doped poly(methyl methacrylate) photopolymer material. Large blocks of samples were made, and the material showed negligible shrinkage after optical exposures. We recorded and reconstructed 250 holograms at a single spot, using a 1‐cm3 block.
