Holographic digital storage with sensitive and flexible photo-initiated polymerization recording

Summary form only given.Volume holographic recording of information is an attractive solution for the next generation of digital storage, holding promise for systems with high density (/spl ges/10 Gbit/cm/sup 2/), and fast transfer rate (Gbit/sec). The performance of a holographic storage system is principally determined by the recording medium characteristics. Photorefractive crystals had been the most extensively investigated volumetric media, offering good optical quality, and sensitive, but typically volatile, recording. Recently, advances in sufficiently thick photopolymerizable recording media have provided a very attractive alternative for WORM systems. This work evaluates the recording physical properties of photopolymer holographic storage.
