    Abstract: A light modulation device capable of stabilizing a phase set in phase modulation processing and improving optical communication quality. A phase modulator is provided for each of plural branched input lights and performs phase modulation of the input light. A phase shifter is provided at the upstream or downstream of the phase modulator and shifts a phase of the input light or of the phase-modulated light. A light interference section causes the output lights from the light modulator to interfere with each other to generate a multilevel phase modulated signal and interference light having a phase state different from that of the modulated signal. A monitor receives the interference light and outputs an electric signal according to the intensity. A phase shift controller generates a phase control signal based on the electric signal and applies the signal to the shifter to control the phase shift amount to be set by the shifter.

    Abstract: In an optical receiver, a light receiving element receives the optical packet signals and converts the optical packet signals to electrical signals. A bias voltage supply section supplies bias voltage to the light receiving element. A monitoring section monitors an input level of each optical packet signal or each electrical signal and transmits a monitored value to the bias voltage supply section. In addition, the bias voltage supply section temporarily increases the bias voltage according to magnitude of the monitored value after an end of receiving of each optical packet signal.
