Based on the structure and network model of the optical fiber sensor with piezoelectric ZnO coating, a target function model for piezoelectric reflection coefficient is presented in this paper. A Niche particle swarm optimization algorithm combined with crossover operator is proposed. The convergent precision is improved for the optimized piezoelectric reflection coefficient and it＇s incident wave receiving efficiency has been greatly improved. A set of optics parameters data can be obtained from the simulation results which provide theoretical references for the fabrication of the fiber sensor with piezoelectric ZnO coating.
