Paper Abstract

High-frequency response (about 50 MHz) is reported for a fiber-optic phase modulator that is coated with vinylidene fluoride/trifluoroethylene (VDF/TrFE) copolymer, 80 about 90 microns thick, on a single-mode fiber of 80 microns diameter and made piezoactive by radial poling. A flat response of optical phase shifts is observed in the frequency range over 10 KHz to 3 MHz whereas at frequencies higher than 4 MHz it shows multiple peaks dominated by radial resonances of the fiber-jacket composite. An excellent agreement exists between the experimental data and theoretical calculations based on radial vibration analysis.
