Abstract

This paper addresses the issues associated with simultaneous achievement of high capacity, high data rate, and a short access time in volume holographic memories. We show that fundamental limits impose performance tradeoffs in any volume holographic memory system. When combined with the state of the art in compact lasers, spatial light modulators, and detector arrays, the overall performance of these memories can be bounded. Achieving greater performance will require either significant improvements in these components, or memory architectures which permit parallel storage systems to be used to increase the capacity or data rate. Conversely, component performance requirements should be evaluated within the context of an entire memory system.
