摘要

An experimental study was conducted to realize parallel optical digital operations using multiple beam interference in cascaded Mach-Zehnder and Michelson interferometers. Considering light intensity at different points of 2-D interference pattern as output, which is controlled by intensity of two input beams in the arms of Mach-Zehnder and Michelson interferometers, respectively, two input multiple AND, OR, NAND, NOR, XOR and XNOR optical logic gates are demonstrated simultaneously. Further, a scheme was proposed to use these simultaneous logic operations, in designing integrated photonic circuits. Proposed scheme may have potential application in ultrafast information processing due to parallel multiple logic operations using the least number of electro-optic/all-optical switches, e.g. using only two photonic switches in the input arms in the present case.
