For polarization imaging, the wire-grid polarizer is one of the most popular devices. We designed and fabricated a pixel polarizer array (PPA) based on a wire-grid polarizer at 700–900 nm wavelength. We studied the influence of different structural parameters on the extinction ratio and transverse magnetic (TM) mode transmissivity of the system. Simulations of the PPA performance using the optimal structure were conducted and a complete PPA fabrication flow was introduced. The polarization charactePixel polarizer array, Polarization technology, Wire grid, Extinction ratioristics and appearance of the PPA was observed using polarizing and scanning electron microscopies, which preliminarily confirm the accuracy of the design results and the feasibility of the processing technology..
