英文摘要	In this paper, a complete investigation and simulation of the extinction ratio (ER) in a setup with a micro-polarizer array (MPA) is performed. A metal grid substrate structure, which can effectively reduce optical crosstalk and improve the ER, is proposed. The numerical calculation results show that the ER of our proposed structure is more than 10-fold higher than that of the traditional structure. Moreover, the effect of its structural parameters to the ER has been researched, and the results showed that when the substrate is thicker, the incident angle of light is less than 15 degrees, the metal width is larger than 900 nm, and a complete grating with more than 20 periods on a single pixel can obtain a high ER.(c) 2022 Optica Publishing Group
