摘要：
In this paper, a novel optical comparison operation for PSK-modulated signal has been proposed by using optical delayed interferometer to realize an advanced functional component for future optical network. The feasibility of the optical comparators designed for 4-bit and 6-bit codewords was experimentally demonstrated. It has been shown that the constellations obtained from each comparator are located in conformity with a Hamming distance between a comparator code and a given codeword, which is comprised of a successive two and three QPSK-modulated RZ symbols at 10.72 Gbaud/s. It was concluded that the proposed scheme offers a comparison operation for 4-bit and 6-bit codewords at 10 Gbaud/s.
