Suppression of radiation loss in high kinetic inductance superconducting co-planar waveguides
S. Hähnle, N. v. Marrewijk, A. Endo +4
We present a novel lab-on-chip technique to measure the very low losses in superconducting transmission lines at (sub-) mm wavelengths. The chips consist of a 100 nm thick NbTiN Co…
DESHIMA on ASTE: On-sky Responsivity Calibration of the Integrated Superconducting Spectrometer
Tatsuya Takekoshi, Kenichi Karatsu, Junya Suzuki +36
We are developing an ultra-wideband spectroscopic instrument, DESHIMA (DEep Spectroscopic HIgh-redshift MApper), based on the technologies of an on-chip filter-bank and Microwave K…
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…
Mitigation of Cosmic Ray Effect on Microwave Kinetic Inductance Detector Arrays
K. Karatsu, A. Endo, J. Bueno +6
For space observatories, the glitches caused by high energy phonons created by the interaction of cosmic ray particles with the detector substrate lead to dead time during observat…
Wideband on-chip terahertz spectrometer based on a superconducting filterbank
Akira Endo, Kenichi Karatsu, Alejandro Pascual Laguna +16
Terahertz spectrometers with a wide instantaneous frequency coverage for passive remote sensing are enormously attractive for many terahertz applications, such as astronomy, atmosp…
Surface wave control for large arrays of microwave kinetic inductance detectors
Stephen J. C. Yates, Andrey M. Baryshev, Ozan Yurduseven +8
Large ultra-sensitive detector arrays are needed for present and future observatories for far infra-red, submillimeter wave (THz), and millimeter wave astronomy. With increasing ar…
