Abstract
In a Michelson inteferometer with phase conjugate mirrors at least one of such mirrors includes a Kerr medium. This enables control over the relative phases of the beams that are reflected from the mirrors and superimposed to form an output beam. The interferometer can be used to perform a logic function by interposing transparencies in the reflected beams. By appropriate choice of the relative phases a logic OR function can be achieved.
