Abstract

A novel three-dimensional optical memory system based on a light transducing protein, bacteriorhodopsin, is investigated. The system uses the nonlinear optical properties of bacteriorhodopsin to accomplish reading and writing operations. A nondestructive method of reading information in three-dimensional optical memory that uses second harmonic generation is demonstrated. This method has the advantage of fast speed, is nondestructive, and has the potential for parallel access.
