Abstract

72583-Holographic optical memory holds great potential for high-capacity, high-speed storage and access of data, particularly in nuclear research, where a continuous stream of data at a rate of 100¿megabytes per second or more may need to be stored, with a total annual data volume of several hundred terabytes. However, current data storage systems are limited in terms of both storage capacity and access time. This project will develop a novel three-dimensional volume, fast access holographic data storage system. The proposed system is based on unique speckle-encoded reference beam multiplexing in 90-degree recording geometry, which overcomes the limitations of the current holographic optical memory technology. Phase I performed a system design and analysis, selected key components, constructed a laboratory breadboard, and conducted a proof-of-principle experimental demonstration. The recording and retrieval of holograms in 90 degree geometry, with a two-dimensional shift-multiplexed speckle-encoded reference beam in a photorefractive crystal recording medium, was successfully demonstrated. In Phase II, a fully-operational, prototype three-dimensional holographic archival memory system will be designed and developed. The system will consist of a holographic recording/retrieval optoelectronic assembly with a removable holographic medium module and an electronic interface for users. The system will be capable of storing 100 terabits of data at a data rate of 10 gigabits per second. Commercial Applications and Other Benefits as described by awardee: The new high capacity, high speed, holographic memory system should lead to ultrahigh-capacity data storage with the capability of random access at high speed as well as content-addressable search without moving the recording medium. Commercial applications include large- scale data storage, computation, optical communication, and image archiving in libraries and in medical, university, and research facilities.
