An optical computer arithmetic/logic unit using coherence multiplexing. A optical signal input into the device is distributed down two input channels. Each input channel contains different length optical fibers, or delay lines. To perform an operation, one delay line signal from each channel is selected. The two signals with their respective delays are multiplexed into output detectors which determine from optical interference the difference between the delay line lengths. The input from each channel coupled with the detected output can be set to perform residue arithmetic, or Boolean logic.
