| Abstract(in English) | Optical processing is expected in routing nodes for photonic networks. In label routing networks, a device to recognize optical labels is one of the key devices. We have proposed a waveguide device for recognizing optical Quadri Phase Shift Keying (QPSK) code. The phase identification device for the QPSK optical code consists of a 3dB directional couple, two Y-junctions and an asymmetic X-junction. By using interference between an optical QPSK pulse and a reference bit pulse, the device distinguishes the optical phase. QPSK codes consisting of plural bits can also be recognized by connecting the basic module devices in a tree structure through a phase adjustment circuit. In this paper, we present BPM simulation results of recongnition device for two-bits QPSK labels to confirm the proposed operation and discuss the wavelength dependence. |
