We design and optimize the sandwiched reflective polarization-selective grating in Littrow mounting. By using the modal method and the rigorous coupled-wave analysis, grating parameters are analyzed and calculated including grating groove depth, thickness of connecting layer, and so on. The grating device can diffract the transverse electric-polarized plane light only in the -1st diffractive order with high reflection efficiency of 97.91%. Meanwhile, for the transverse magnetic-polarized plane light, diffraction efficiencies in the 0th order and the -1st order correspond to 48.67% and 48.68%, respectively..
