High optical efficiency and photon noise limited sensitivity of microwave kinetic inductance detectors using phase readout
R. M. J. Janssen, J. J. A. Baselmans, A. Endo +4
We demonstrate photon noise limited performance in both phase and amplitude readout in microwave kinetic inductance detectors (MKIDs) consisting of NbTiN and Al, down to 100 fW of…
Design and Testing of Kinetic Inductance Detectors Made of Titanium Nitride
P. Diener, H. G. Leduc, S. J. C. Yates +2
To use highly resistive material for Kinetic Inductance Detectors (KID), new designs have to be done, in part due to the impedance match needed between the KID chip and the whole 5…
Fluctuations in the electron system of a superconductor exposed to a photon flux
P. J. de Visser, J. J. A. Baselmans, J. Bueno +2
We report on fluctuations in the electron system, Cooper pairs and quasiparticles, of a superconducting aluminium film. The superconductor is exposed to pair-breaking photons (1.54…
Evidence of a nonequilibrium distribution of quasiparticles in the microwave response of a superconducting aluminium resonator
P. J. de Visser, D. J. Goldie, P. Diener +3
In a superconductor absorption of photons with an energy below the superconducting gap leads to redistribution of quasiparticles over energy and thus induces a strong non-equilibri…
On-chip filter bank spectroscopy at 600-700 GHz using NbTiN superconducting resonators
A. Endo, C. Sfiligoj, S. J. C. Yates +6
We experimentally demonstrate the principle of an on-chip submillimeter wave filter bank spectrometer, using superconducting microresonators as narrow band-separation filters. The…
