  • Apparatus and Method for Generating an Optical Single Sideband Signal
    Publication number: 20080002989
    Abstract: A single sideband signal is generated from an input optical signal. An optical phase modulator performs optical phase modulation on the input optical signal in accordance with a control signal to produce the single sideband signal. A converter converts the input optical signal into a corresponding electrical signal. A control signal generator generates the control signal in response to an optical signal pulse shape of the input optical signal.
