Outline of Final Research Achievements

Optical signal processing circuits for high-speed low-power-consuming label routing systems requited in future photonic networks were studied.
Optical label recognition circuits for coded labels in binary phase-shift-keying (BPSK), quadrature PSK (QPSK), and quadrature amplitude modulation (QAM) formats were proposed and the recognition functions were theoretically clarified. Optical switches, optical flip-flop circuits, and optical buffer systems required for routing processing were proposed and the fundamental characteristics were theoretically and experimentally investigated.
Optical modulation-format conversion systems between BPSK and QPSK packets requited for spectrally-efficient and flexible networking were proposed and theoretically and experimentally investigated.
