Abstract

The lack of a suitable recording material has long been the Achilles heel of holographic storage. In contrast to the other system components (such as SLM, laser and detector array) which are generally available, although they may not be optimized for this particular application, the ideal material has yet to be developed. As a result, after 30 years of on-and-off development, no commercial digital holographic storage system has yet been deployed To address this bottleneck, the PRISM (photorefractive information storage materials) consortium was formed in 1994 to focus on the development of a suitable recording material and to understand how storage system trade-offs are affected by each candidate material system.
