Abstract:
1. A device operable to detect polarized light comprising: a substrate; a first subpixel; a second subpixel adjacent to the first subpixel; a first plurality of features in the first subpixel and a second plurality of features in the second subpixel, wherein the first plurality of features extend essentially perpendicularly from the substrate and extend essentially in parallel in a first direction parallel to the substrate and the second plurality of features extend essentially perpendicularly from the substrate and extend essentially in parallel in a second direction parallel to the substrate; wherein the first direction and the second direction are different; the first plurality of features and the second plurality of features react differently to the polarized light; wherein each of the first plurality of features comprises a p-i-n diode or forms a p-i-n diode with the substrate, and wherein the p-i-n diode is functional to convert at least a portion of the polarized light to an electrical signal.
