![عکس صفحه اول مقاله: Connecting-layer-based polarizing beam splitter grating with high efficiency for both TE and TM polarizations Connecting-layer-based polarizing beam splitter grating with high efficiency for both TE and TM polarizations](/preview/png/732385.png)
We describe a novel polarizing beam splitter (PBS) of transmission connecting-layer-based grating, which can show high efficiency for TE polarization in the −1st order and TM polarization in the 0th order. According to the modal method, grating duty cycle and period are prescribed to obtain high efficiency for TM polarization. Using the rigorous coupled-wave analysis, grating depth and thickness of the connecting layer are optimized to achieve high efficiency for TE polarization. The presented PBS has advantages of wideband properties for incident wavelength and angle. Most importantly, the efficiency is improved greatly for TE polarization compared with the reported PBS based on fused-silica grating.
