Abstract
An optical logic circuit includes a NOT circuit. The NOT circuit reflects by fixed end reflection an data pulse input into the optical logic circuit which is an ON pulse of which a wavelength and an intensity are similar to a wavelength and an intensity of a standard optical pulse or an OFF pulse obtained by applying OFF modulation to the standard optical pulse. The NOT circuit multiplexes the reflected data pulse and the standard optical pulse and outputs the multiplexed pulse.
