Abstract

The general problem is as follows: Given a number of binary optical inputs, photodetectors thresholded to provide binary outputs, and a desired functional relationship (memory-free) between the inputs and outputs, find an optimum assembly of passive optical elements that implements the relationship. Here the passive optical elements might be diffracting, shadowing, reflecting, or refracting structures of various numbers, locations, sizes, and shapes; the binary optical inputs might be from a spatial light modulator or an array of laser diodes; the desired relationship might be a combinational logic function with a high proportion of don't-cares (input values or patterns for which the output may be either binary value); and optimality might be specified in terms of maximum fabrication and operating tolerances or minimum complexity. Several aspects of this general problem are considered in the context of optical real-weight and complex-weight threshold logic and optical binary pattern classification.
