Abstract
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 2.257×103. 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..
