Abstract
By inputting a modulation signal from a synthesizer circuitto a switching circuitvia isolator elementsA,B by inserting the isolator elementsA,B between the synthesizer circuitand the switching circuit, an operation of the synthesizer circuitis prevented from being unstable with a load fluctuation by an opening or a short-circuit of circuits after the switching circuit, so an operation of the synthesizer circuitwill not be unstable by a load fluctuation when switching driving signals supplied to optical comb generatorsA,B by the switching circuit, and a driving state is transited by switching the driving signals of the optical comb generatorsA,B rapidly.
