Optical adder that uses spatial light rebroadcasters

Abstract

We show novel experimental results for an all-optical cascadable module that consists of a spatial light rebroadcaster, an image intensifier, and a liquid-crystal light valve. The module may be used for all-optical logic, memory, or arithmetic. Previous experimental systems involving spatial light rebroadcasters use a video camera and computer to overcome their lack of cascadability. The results of laboratory experiments show correct operation for a half-adder constructed from the cascadable module. Optical setups are proposed for constructing all-optical parallel ripple-carry and bit-slice full adders by using a single optical half-adder.
