摘要：

High sensitive response of a fiberoptic phase modulator that is coated with 80 ∼ 90-μm-thick vinylidene fluoride / trifluoroethylene copolymer on an 80-ftm-diameter singlemode fiber and made piezoactive by radial poling is demonstrated over a wide frequency range, from 500 Hz to 50 MHz. In the range of 10 KHz up to 2 MHz, a relatively flat response is measured, whereas at high frequencies between 6 and 50 MHz, the phase modulation exhibits multiple peaks dominated by radial resonances of the fiber-jacket composite. The theoretical considerations on the phase shift are followed by the experiments. © 1990 IEEE
