  • Two-color photo-detector and methods for demosaicing a two-color photo-detector array
    Patent number: 6940061
    Abstract: A two-color photo-detector capable of sensing two colors at a single photo-detector location is provided having a lower photo-detector element resident in the bulk silicon and an upper photo-detector element elevated above the lower photo-detector element. The color sensitivity of each of the photo-detector elements is determined according to the absorption curve of the upper photo-detector element, the thickness of the upper photo-detector element and the color filter array, if any. The elevated upper photo-detector element overlies the circuitry needed for both the upper photo-detector element and the lower photo-detector element. In order to accurately sample color within an array of two-color photo-detectors without a color filter array, two different thicknesses for the upper photo-detector elements of adjacent two-color photo-detectors are used. Therefore, each pair of two-color photo-detectors within the array senses four different colors (i.e.
