  • Patent number: 11011658
    Abstract: Method and system for wavelength thermophotovoltaic (WTPV) power generation. In one embodiment, the system comprises a refractory waveguide that collects broadband infrared light generated by a heat source; a filter that filters the collected broadband infrared light to generate narrow-band infrared light; and a thermophotovoltaic (TPV) converter, thermally de-coupled from the heat source, that receives the narrow-band infrared light and converts the received narrow-band infrared light to electrical power.
    Type: Grant
    Filed: May 9, 2019
    Date of Patent: May 18, 2021
    Assignee: The United States of America as represented by the Secretary of the Army

  • Patent number: 6407439
    Abstract: More than one photodetectors, each sensitive to different wavelengths, are integrated on a common semiconductor substrate. The different photodetectors can be stacked over one another or placed laterally on the common substrate. Gratings may be placed over each photodetector to sharpen the spectral response. Three such photodetectors can form a pixel of an active matrix array for an image sensor. The different photodetectors in each pixel can be multiplexed electronically. The electronic circuits for activating the different photodetectors can be integrated on the same substrate.
