Abstract

The optical fiber acousto-optic sensor (OFS) coated with piezoelectric ZnO has previously been investigated both theoretically and practically. While fabricating OFS, the performance of it will be affected by many parameters. Based on the equivalent circuit's model of cylindrical resonator of acoustic optic devices, an optimization method has been presented in this paper. By considering the effects towards the performance of optical fiber sensor due to some parameters, including electrode's thickness, Piezoelectric ZnO film thickness, the fiber's radius, resonator length, series impedance, and so on, the partial optimization of target functions including reflectance and coupling efficiency is programmed to produce optimized values. Also, combined with the effects of reflectance and coupling efficiency, the optimized values have been made based on the theory of multi-targets optimization.
