Enhanced Mid-Infrared Single-Photon Detection with Antenna-Coupled Superconducting Nanowires
Dip Joti Paul, Stewart Koppell, Gregor G. Taylor +7
Scaling the photon-detection area of superconducting nanowire single-photon detectors (SNSPDs) has traditionally been achieved by nanowire meandering. However, material inhomogenei…
Dark Matter Haloscope with a Disordered Dielectric Absorber
Stewart Koppell, Otavio D. A. R. Bittencourt, Dip Joti Paul +3
Light dark matter candidates such as axions and dark photons generically couple to electromagnetism, yielding dark-matter-to-photon conversion as a key search strategy. In addition…
Photolithography-Compatible Three-Terminal Superconducting Switch for Driving CMOS Loads
Dip Joti Paul, Tony X. Zhou, Karl K. Berggren
Superconducting devices have enabled breakthrough performance in quantum sensing and ultra-low-power computing. Nevertheless, the need for a cryo-electronics platform that can inte…
Determination of Mid-Infrared Refractive Indices of Superconducting Thin Films Using Fourier Transform Infrared Spectroscopy
Dip Joti Paul, Tony X. Zhou, Karl K. Berggren
In this work, we present a technique to determine the mid-infrared refractive indices of thin superconducting films using Fourier transform infrared spectroscopy (FTIR). In particu…
