Two pictures overlapped. In the bottom left picture, a microscope picture of a silicon chip with a blueish green tint and wiring on it. Overlaid over the silicon chip is a some data in the form of a 3D histogram that has a large central hump, representing the arrival of photons in a gaussian-distributed area at the center of the camera. On the upper right pictures, a black and white scanning electron micrograph showing a highly zoomed image of a nanowire structure. The nanowire structure shows white pads on the top of bottom, with a set of horizontal wires that meander back and forth between the top. The scale bars are on the order of 2 micrometers.

Technology Interests

  • Superconducting nanowire single photon detectors
  • Electrothermal nanowire electronics for amplification and readout of superconducting signals
  • Vertically aligned carbon nanotubes
  • Machine learning and optimization frameworks

Goals and Aspirations

  • Creation of a multi-megapixel single photon detector array that has near-unity efficiency and fill factor
  • Integrating carbon-nanotube absorbers with SNSPDS to create broadband single-photon detectors.
  • Increasing the operating temperature of SNSPDs to ease space flight requirements
