Abstract(in English) As the demand for advanced optical network with low power consumption, we experimentally demonstrated a comparison operation by using optical signal processing. The proposed scheme was comprised of a delayed interferometer and phase shifters. In this paper, we experimentally confirmed the feasibility of the optical comparator for 4 and 6 bit QPSK-modulated signal at 10.72 Gbaud.
