The sub-wavelength grating has special characteristics compared to traditional *** to the requirement of the optical communication devices,sub-wavelength grating polarizer was designed based on rigorous coupled-wave theory(RCWA).The paper analyzes the grating parameters such as the period,depth,fill grove that influence the diffraction efficiency of the grating. Calculation results indicate that the diffraction efficiency of sub-wavelength grating changes with the period,the depth of the grove,fill factor,and shape of the grating. The TM mode diffraction efficiency is more than 95%,and the TE mode diffraction efficiency is less than 5%,the pyramidal sub-wavelength polarizer grating has good performance than others shapes in the optical communication band of *** this paper,we designed this kind of sub-wavelength grating polarizer has great potential applying in optical switching,optical memory,optical detectors and other photo-electronic devices.
