In order to design a polarization splitter based on lithium niobate photonic wires, the splitter was analyzed and optimized by using the electromagnetic simulation software based on finite element method and the optimal design result of compact structure size was gotten. The effects of the changes of waveguide width on the transmission of the splitter were analyzed with the consideration of the common process error. The results show that the bandwidth and power transmittance of the polarization splitter have the strong relationship with the waveguide coupling length.
