Optical logic circuit useful for bit serial optic computing

摘要

Optical elements are combined into modules capable of performing logic functions in response to light pulses which are received from a source as clock pulses or data pulses. The module is effectively an all optical switching network. An optical delay line provides optical memory. The pulses that are produced at the delay line output are restored by selective reentry of light pulses from a continuously operable source so that the pulse information is storable indefinitely. The module is useful for a variety of computer and computer related design functions.
