ABSTRACT:
An optical AND gate for use in a cross-bar arithmetic/logic unit including first and second optical substrates which are configured adjacent to one another with each of the optical substrates having a respective plurality of optical paths formed thereon. The pattern of optical paths form a plurality of intersecting regions where the optical paths associated with one of the optical substrates overlaps the optical paths associated with the other optical substrate. The optical substrates are operable for transmitting an incident light beam there through so as to produce an output at one of the intersecting regions. The optical substrates transmit the incident light beam only through the optical paths which have been illuminated by a plurality of light sources.
