摘要：

We describe a high-efficiency polarizing beam splitter (PBS) of deep-etched fused-silica grating based on total internal reflection (TIR) under second Bragg angle incidence. Efficiency can reach 98.27% for TE-polarized wave in the -2nd order and 99.15% for TM-polarized wave in the 0th order, and extinction ratio can reach 2.257x10(3). As an excellent optical material, fused silica can stand with high laser power. TIR grating can realize high efficiency by reflecting all the energy without transmission. It is the first time to present PBS grating based on TIR under second Bragg angle incidence etched in fused silica.
