Counting Near Infrared Photons with Microwave Kinetic Inductance Detectors
W. Guo, X. Liu, Y. Wang +8
We demonstrate photon counting at 1550 nm wavelength using microwave kinetic inductance detectors (MKIDs) made from TiN/Ti/TiN trilayer films with superconducting transition temper…
Optical responses of the switching currents in Al and Nb Josephson junctions
Yiwen Wang, Pinjia Zhou, Lianfu Wei +5
We experimentally demonstrated the optical responses of the switching currents in two types of Josephson tunnel junctions: Al/AlOx/Al and Nb/AlOx/Nb. The radiation-induced switchin…
Photon-induced thermal effects in superconducting coplanar waveguide resonators
Yiwen Wang, Pinjia Zhou, Lianfu Wei +6
We experimentally investigated the optical responses of a superconducting niobium resonator. It was found that, with increasing radiation power, the resonance frequency increases m…
Experimental demonstrations of high-Q superconducting coplanar waveguide resonators
Haijie Li, Yiwen Wang, Lianfu Wei +6
We designed and successfully fabricated an absorption-type of superconducting coplanar waveguide (CPW) resonators. The resonators are made from a Niobium film (about 160 nm thick)…
