Abstract

The ever-increasing demand of high-speed data processing can only be achieved by the active use of all-optical logical and data processing units. Phase-encoded binary data representation scheme is the promising candidate for the next-generation communication system due to its higher spectral efficiencies and hence higher data processing capabilities. In this process, all-optical comparator will play a vital role. In this communication, a novel concept of all-optical single-bit comparator based on phase encoding process is proposed. The processing part of the unit consists of only phase shifters, mirrors and optical coherent mixers. Optical switches are used in encoding and decoding process only. So a real-time operational speed may be achieved.
