摘要：
The present invention is to provide an optical modulating system for generating a signal of a frequency (f 0 +2f m ) and a signal of a frequency (f 0 -2f m ) and suppressing a signal of a frequency (f 0 ) by a DSB-SC modulator.
A fourth harmonic generating system for solving the above problem comprises a first DSB-SC modulator (2) a second DSB-SC modulator (3) and a signal control section (5) for controlling a modulating signal from a signal source (4) for generating modulating signals applied to the first and second DSB-SC modulators (2,3) so that a lower side-band signal (f 0 ) generated by modulating the upper side-band signal of the DSB-SC modulator (2) by the DSB-SC modulator (3) and an upper side-band signal (f 0 ) generated by modulating the lower side-band signal of the DSB-SC modulator (2) by the DSB-SC modulator (3) cancel each other.
