Abstract
By inputting a modulation signal from a synthesizer circuit 11 to a switching circuit 13 via isolator elements 12A, 12B by inserting the isolator elements 12A, 12B between the synthesizer circuit 11 and the switching circuit 13, an operation of the synthesizer circuit 11 is 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 circuit 11 will not be unstable by a load fluctuation when switching driving signals supplied to optical comb generators 14A, 14B by the switching circuit 13, and a driving state is transited by switching the driving signals of the optical comb generators 14A, 14B rapidly.
