    "abstract": "I propose a new optoelectronic device that completely and instantaneously\nmeasures the incident light\u0027s polarization for a narrow wavelength band in a\nsingle physical pixel. The device has four (or more) quantum-well active\nregions separated and topped by four (or more) linear gratings at different\norientations. Electrical contact is made to each grating and to a bottom\ncontact layer to measure four (or more) photocurrents. The device uses\ninterference among many light paths to encode in four photocurrents four values\nthat completely describe the polarization state of the incident light at a\ngiven wavelength. I begin with the motivation for the new device. Then, I\nreport on two computational models: the first includes perfectly conducting\ngratings, and the second includes more realistic dielectric gratings. Next, I\nwill describe the design and processing of a two-layer proof-of-concept device.\nLast, I will recount the trials of the first round of fabrication.",
