Abstract : This Final Report describes the results of a Phase I SBIR project to investigate the feasibility and practicality of utilizing Spectral Hole Burning (SHB) media as the basis of a high capacity optical memory system. Our concept has the potential for providing enormous storage capacities (on the order of 10th to the 12th power bits and larger) in commercially viable systems. This report summarizes our analyses and shows that the necessary system components as well as material properties presently exist (or are under rapid development) which can make such a memory system a practical reality and not simply a theoretical possibility. The ultimate system design is expected to be a high capacity unit of modest physical size which has low power requirements, high data rate, and an access time suitable to be useful to a broadbased user community.
