Paper Abstract

Previous optical computing schemes offered analog or quasi-digital accuracies with a single fixed primitive. This paper describes how programmable, arbitrary bit length all digital Central Processing Unit (CPU) computations are now possible by using control logic to compute ALU primitives for emulating a general purpose programmable computer. These primitives are then executed sequentially in order to calculate 32 bit or larger primitives. This paper innitially discusses the theoretical background which addresses Shannon's expansion theorem, Morozov's control operator method, coupled with DeMorgan's laws. These three ingredients are then mapped onto current optical computer hardware technology using laser diode arrays, multichannel acousto-optic spatial light modulators, and avalanche photodiode arrays.
