Paper Abstract

Reversible photoinduced anisotropy of polymer films with protein bacteriorhodopsin (BR) have attracted a lot of attention for real time optical processing [1, 2]. The high photosensitivity of these films allows the processing of low-power optical signals (several milliwatt CW visible laser irradiation). Spatial resolution does not fall below 5000 lines/mm, require no external processing, and images can be recorded and erased over <106 cycles without degradation. Compared with the photorefractive crystal, BR polymer films offers the advantages of lower intensity requirement and much larger space-bandwidth-product. This work shows possibility of the application of BR polymer films for the light polarization modulator with purely optical control and for real time selective image processing resulting from photoinduced anisotropy of BR polymer films.
