Paper Abstract

The performance of optically bistable liquid crystal interference filters with extra-cavity metallic absorbers is contrasted with designs using intra-cavity dyes with which switching levels at 4 pW are recorded. The use of these devices in parallel processing applications is also considered, with the optical implementation of a "flip-flop" and results of a 15 x 15 element array switching presented.
