Holographic memory in solid state architecture

摘要

Number of applications require technology that allows storing, retrieving, and processing a large volume of information. Holographic memory offers high-density data storage with parallel access and high throughput. Several methods exist for data multiplexing based on the fundamental principles of volume hologram selectivity. We recently demonstrated that a spatial (amplitude-phase) encoding of the reference wave (SERW) looks promising as a way to increase the storage density. The SERW hologram offers a method other than traditional methods of selectivity, such as spatial de-correlation between recorded and reconstruction fields. In this report we present the experimental results of the SERW-hologram memory module with solid-state architecture, which is of particular interest for space operations.
