Abstract

By developing an exact theory from the device structure based on the actual cylindrical nature of the transducer, an electrical model of the optical-fiber acousto-optic fiber phase-modulator (OFPM) coated with piezoelectric ZnO has been presented. Then, full details for the acoustic transducer resonator have been investigated, which are vital considerations in transducer design. Finally, to evaluate the validity of the model and the parameters deduced from that model, we use the practical coefficients and parameters in theoretical calculations. An excellent agreement exists between the model simulation results and experimental measurements.
