中文摘要	we investigated the use of a deep-etched fused-silica grating with triangular-shaped grooves as a highly efficient polarizing beam splitter (pbs). a triangular-groove pbs grating is designed at a wavelength of 1550 nm to be used in optical communication. when it is illuminated in littrow mounting, the transmitted te- and tm-polarized waves are mainly diffracted in the minus-first and zeroth orders, respectively. the design condition is based on the average differences of the grating mode indices, which is verified by using rigorous coupled-wave analysis. the designed pbs grating is highly efficient over the c+l band range for both te and tm polarizations (> 97.68 %). it is shown that such a triangular-groove pbs grating can exhibit a higher diffraction efficiency, a larger extinction ratio, and less reflection loss than the binary-phase fused-silica pbs grating.
