Abstract

We have presented an integrated Division-of-Focal-Plane spectral-polarization sensor in this paper. The sensor monolithically integrates pixelated aluminum nanowire polarization filters with an array of vertically stacked photo detectors. Each individual pixel in the imaging array is composed of three vertically stacked photo detectors together with the necessary read-out electronics, such as source follower, reset transistor and address transistor. The pixelated polarization filter array is composed of four distinct linear polarization filters oriented at 45 degrees from each other. The complete sensor is capable of sensing both spectral and polarization information across the visible spectrum at 4 frames per second. A summary of the imaging sensor characteristics is provided in Table 1.
