Abstract

The application of dry purple membrane films for nonlinear-optical filtering is described. The biological photo-chrome bacteriorhodopsin (BR) is contained in the purple membrane (PM) from Halobacterium halobium. BR has two dominant photoactive states, B and M, which have well-separated absorption bands with maxima at 570 nm (B) and 412 nm (M). Since the local transmission of a PM film depends on the ratio between the forward (B → M) and the backward (M → B) photoreactions, PM films can be used as light-controlled absorptive spatial light modulators. A model describing the nonlinear transmission of PM films containing the wild-type form of BR or one of its mutated variants, e.g., BRD96N, and examples of their application in spatial filtering, e.g., edge enhancement, are presented.
