In order to obtain a grating-based polarizer with high efficiency and high extinction ratio, we proposed a multilayer metal-coated nano-grating operated at the wavelength of 1550 nm. Different from previous most reported structures, the suggested structure of the grating works at the incident angle 45 degrees, so that the reflection direction is perpendicular to the transmission direction. The reflection extinction ratio and transmission extinction ratio can reach 49.15 dB and 55.49 dB, respectively. The metal layer and Ta2O5 dielectric layer are added to improve the performance of the grating. Most importantly, the results show that the extinction ratio of the two orthogonally polarized components of light can be larger than 20 dB within angular width 26.1°, between 29.1−55.2°. The grating can be widely used in liquid crystal display devices owing to its small size and strong anti-interference ability.
