Resolving Power of Visible to Near-Infrared Hybrid -Ta/NbTiN Kinetic Inductance Detectors
Kevin Kouwenhoven, Daniel Fan, Enrico Biancalani +7
Kinetic Inductance Detectors (KIDs) are superconducting energy-resolving detectors, sensitive to single photons from the near-infrared to ultraviolet. We study a hybrid KID design…
A Composite Phononic Crystal Design for Quasiparticle Lifetime Enhancement in Kinetic Inductance Detectors
Tuomas A. Puurtinen, Karwan Rostem, Pieter J. de Visser +1
A nanoscale phononic crystal filter (reflector) is designed for a kinetic inductance detector where the reflection band is matched to the quasiparticle recombination phonons with t…
First light demonstration of the integrated superconducting spectrometer
Akira Endo, Kenichi Karatsu, Yoichi Tamura +36
Ultra-wideband 3D imaging spectrometry in the millimeter-submillimeter (mm-submm) band is an essential tool for uncovering the dust-enshrouded portion of the cosmic history of star…
Enhanced quasiparticle lifetime in a superconductor by selective blocking of recombination phonons with a phononic crystal
K. Rostem, P. J. de Visser, E. J. Wollack
When quasiparticles in a BCS superconductor recombine into Cooper pairs, phonons are emitted within a narrow band of energies above the pairing energy at 2. We show that a phono…
Spatial conductivity mapping of unprotected and capped black phosphorus using microwave microscopy
Pieter J. de Visser, Rebekah Chua, Joshua O. Island +5
Thin layers of black phosphorus present an ideal combination of a 2D material with a tunable direct bandgap and high carrier mobility. However the material suffers from degradation…
The non-equilibrium response of a superconductor to pair-breaking radiation measured over a broad frequency band
P. J. de Visser, S. J. C. Yates, T. Guruswamy +7
We have measured the absorption of terahertz radiation in a BCS superconductor over a broad range of frequencies from 200 GHz to 1.1 THz, using a broadband antenna-lens system and…
