Circular Polarimetric Imaging with a Metamaterial Integrated Long-Wavelength Infrared Focal Plane Array.

ABSTRACT: Long-wavelength infrared (LWIR) circular polarimetric imaging plays an important role in many areas. The immediacy of polarimetric imaging and the miniaturization of devices drive considerable efforts to division-of-focal-plane-array (DoFPA) circular polarimeters. However, the realization of such detectors is hampered by low polarization discrimination, reduced absorption in the detection material, and fabrication complexity. The situation becomes more serious in the LWIR range since the pixel size is only a few wavelengths of the incident light. Here, a quantum well infrared photodetector based LWIR DoFPA circular polarimeter featuring a 320 × 256 pixel array integrated with a chiral meta-mirror array is established. The spectral range of this detector is from 10 to 11 µm. Taking advantag
