Paper Abstract

Certain optics-based register-level devices for digital processing applications are considered. These modular devices have electronic binary inputs and outputs and are based on the electro-optic intensity modulation of near-surface light. The modulation technique combines features of a total internal reflection electro-optical spatial light modulator and a Lloyd's mirror interferometer. The devices may be described as threshold logic elements for which the analog weighting and thresholding operations are effectively implemented using integrated (or near-integrated) optical technology. Such an effective implementation, which is difficult at best using current all-electronic technology, is important because digital processing systems using threshold logic elements require no more and often many fewer interconnections and logic levels than do similar systems using conventional logic gates. Fewer interconnections and logic levels may in turn provide the foundation for exceptionally high-speed, low-power-consumption, small-size, and otherwise attractive digital processing systems.
