Holographic data storage using photopolymer

Abstract

We present our studies on a photopolymer of poly(methyl methacrylate) (PMMA) doped with phenathrenequinone (PQ) molecules. We describe their characteristics for holographic data storage, including photo-sensitivity, material M/#, angular selectivity, dynamic exposure schedule, absorption and scattering effect. Experimental demonstrations on multiple digital data pages stored in a polymer cube are presented.
