Abstract
A method of performing optical serial-to-parallel conversion of an optical signal includes performing phase modulation of the optical pulse stream and outputting a phase-modulated optical signal. Optical switching of the phase-modulated optical signal is performed by optical switches provided on a signal path. Optical switching of a reference optical clock signal is performed by optical switches provided on a reference path. I/Q demodulation of the optically switched phase-modulated optical signal respectively output by an optical switch is performed on the signal path at timings corresponding to the optically switched reference optical clock signal respectively output by an optical switch on the reference path, in which I and Q demodulated signals are output as a result thereof. Photodetection of the I and Q demodulated signals is then performed.
