Abstract

Holographic data storage in BR (bacteriorhodopsin) films has been investigated. The BR film has a fast response time, with high quantum efficiency, high sensitivity, and high spatial resolution. Because of these properties, BR film is attractive as an optical storage medium. Moreover, due to the high spatial resolution, a multiplexing storage scheme can be applied to store a large amount of data. We have demonstrated the possibility of using a phase-multiplexing technique to store the data in BR films. We also show the possibility of using phase masks for spectrum spreading and encoding.
