摘      要：A new modulator for the optical signal in a fiber based on multi-beam interference is *** the experiment,the distance of a couple of abutted fibers was modulated through a piezoelectric ceramic pipe driven by 50 Hz AC voltage,so that the amplitude of the transmitted optical signal was *** modulation ratio is about 10%,S/N ratio is about 60 dB and the bandwidth is about 200 KHz.
