摘要：An optical A/D converter according to the present invention includes an optical
splitter that splits an analog input signal light into plurals, a plurality of Mach-Zehnderinterferometers to which each of the signal lights split by the optical splitter is input, andplurality of optical/electrical conversion unit that convert each signal lights output fromeach Mach-Zehnder interferometer into a digital electrical signal, in which each Mach-Zehnder interferometer includes optical intensity-to-phase conversion unit that opticallyconvert intensity of the input signal light into an amount of phase shift and the amount ofphase shift differs for each Mach-Zehnder interferometer. Then, it is possible to provide ahigh speed and low power consuming optical demodulation circuit.
