    Abstract:

    Due to the close pixel size and working wavelength of the focal plane polarization integrated infrared detector, diffraction effects cause severe crosstalk between adjacent pixels with different polarized light. A single traditional metal grating structure cannot achieve high extinction ratio polarization detection chips. This article proposes and designs a metasurface lens stacked polarization integrated infrared detector structure, studies the optical field convergence ability of metalens for different wavelengths of infrared light waves, prepares metastructural lenses and submicron grating structures, and integrates them with infrared focal planes. The polarization extinction ratio of the device exceeds 15:1, and dynamic and variable temperature objects are selected for polarization imaging experiments, demonstrating the imaging advantages of polarization integrated devices with focal planes.
