A sensor is provided that combines monolithically-integrated pixelated aluminum nanowires with vertically stacked photodetectors. The aluminum nanowires are arranged as a collection of 2-by-2 pixels, or super-pixels. Each super-pixel includes nanowires at four different orientations, offset by 45°. Thus, the optical field is sampled with 0°, 45°, 90°, and 135° linear polarization filters. Due to the spatial subsampling, interpolation may be applied to reconstruct the full 0°, 45°, 90°, and 135° arrays. |
