CONSTITUTION:A correlation signal generating part 103 is inputted with 2 systems of the light puls; the signal light puls of the puls to be synchronized inputted from the outside and a part of the clock light puls outputted from a clock light pul generating part 105 and outputs the electric signal of the sufficiently low speed corresponding to the correlation signal of the light intensities of the two systems. A control circuit 104 calculates the repeating frequency difference of the signal light and the clock light from the output waveforms of a correlation signal generating part 103 and outputs the control signal corresponding to the frequency difference. The clock light pul generating part 105 controls the repeating frequency of the clock light puls by the control signal outputted from the control circuit 104 in such a manner as to have the repeating frequency equal to the clock frequency of the signal light puls. The high-speed optical PLL circuit which is not subjected to the limitation of the operating speed of the electric circuit, etc., is thereby obtd.
