Subject of study. A multilayer semicircle reflective polarization­selective beam splitter is proposed by semicircle grating scheme in this paper. Purpose of the work. With the characteristics of polarization selectivity, the beam splitter grating can separate the incident light into three orders (0th order and ±1st orders) for transverse electric polarization and two orders (–1st order and 1st order) for transverse magnetic polarization, respectively. In this work, the proposed splitter achieves the beam polarization selectivity under normal incidence. Method. The finite element method is a commonly used analysis method to research micro­nano­optical devices, which can use the mathematical approximation to simulate the real physical system. It is used to calculate the optimal parameters of the proposed polarization­selective beam splitter in this research. Main results. By a series of accurate calculations, it is found that the total diffraction efficiencies of transverse electric polarized light can reach 97.27% and transverse magnetic polarization polarized light can reach 96.88% under the optimal grating parameters. It can be found that the grating possesses high efficiency and high reflection optical properties. When the grating parameters such as the grating period and grating thickness fluctuate within a certain range, the impact of the effect of splitting is not big, which means the tolerance is good. Practical significance. The polarization­selective splitter by dual­structure scheme has the certain application value for optical fiber communication and laser system.
