High Speed Random Access, Fourier Transform Holographic Associative And HighDensity Two-Photon Three-Dimensional Optical Memories Based On Bacteriorhodopsin

摘要

The goals of this research and development program were to optimizebacteriorhodopsin based photochromic and photorefractive materials for use in optical memories. Two spatial light modulators (SLMs) based on bacteriorhodopsin were developed, one that could be controlled via applied voltage and the other controlled by light. The former performed below target specification; whereas the latter achieved diffraction efficiencies two-fold above target. Preliminary results on the three-dimensional data cube were sufficiently exciting to adjust the first year statement of work to also include the optimization of the bacteriorhodopsin data cube. (AN).
