    Abstract: An apparatus is provided for nanoantenna-enhanced detection of infrared radiation. The apparatus includes one or more detector pixels. A plurality of detector pixels can constitute a focal plane array (FPA). Each detector pixel carries at least a first and a second subpattern of nanoantenna elements, with elements of the second subpattern interpolated between elements of the first subpattern. Each detector pixel also includes separate collection electrodes for collecting photogenerated current from the respective subpatterns.

  • Patent number: 11482560
    Abstract: A monolithically integrated, tunable infrared pixel comprises a combined broadband detector and graphene-enabled tunable metasurface filter that operate as a single solid-state device with no moving parts. Functionally, tunability results from the plasmonic properties of graphene that are acutely dependent upon the carrier concentration within the infrared. Voltage induced changes in graphene's carrier concentration can be leveraged to change the metasurface filter's transmission thereby altering the “colors” of light reaching the broadband detector and hence its spectral responsivity. The invention enables spectrally agile infrared detection with independent pixel-to-pixel spectral tunability.

  • Patent number: 11296240
    Abstract: A rectenna is used for full-wave rectification of infrared radiation to produce electricity. In the rectenna, a metallic grating overlies a semiconductor body. A tunnel barrier is interposed between each grating element and the semiconductor body. Each of the grating elements overlies a bridge pair consisting of a region of n+-doped semiconductor and a region of p+-doped semiconductor, both of which are embedded in more lightly doped host semiconductor material. Each of the two regions that compose the bridge pair forms a rectifying tunnel junction through a tunnel barrier to at least one overlying grating element. Each of the two regions also forms a semiconductor junction with the host semiconductor material.

  • Patent number: 11287536
    Abstract: A radiation field is detected or imaged using one or more junction devices in which a two-dimensional conductor layer is capacitively coupled to a semiconductor absorber layer. In the junction devices, pixel-level amplification and read-out are accomplished through the photogating of the devices by absorption within the absorber layer while it is in a state of deep depletion. When the two-dimensional conductor is graphene, we refer to a device operating in that manner as a deeply depleted graphene-oxide-semiconductor (D2GOS) detector.

  • Patent number: 10877194
    Abstract: An actively tunable optical filter can control the amplitude of reflected infrared light. The filter exploits the dependence of the excitation energy of plasmons in a continuous and unpatterned sheet of graphene, on the Fermi-level, which can be controlled by conventional electrostatic gating. An exemplary filter enables simultaneous modification of two distinct spectral bands whose positions are dictated by the device geometry and graphene plasmon dispersion. Within these bands, the reflected amplitude can be varied by over 15% and resonance positions can be shifted by over 90 cm?1. Electromagnetic simulations verify that tuning arises through coupling of incident light to graphene plasmons by a nanoantenna grating structure. Importantly, the tunable range is determined by a combination of graphene properties, device structure, and the surrounding dielectrics, which dictate the plasmon dispersion. Thus, the underlying design is applicable across a broad range of infrared frequencies.
