Oral Contribution
We describe the fabrication of homogeneous sub-stoichiometric
titanium nitride films for microwave kinetic inductance detector (KID) arrays. Using a 6” sputtering target and a homogeneous nitrogen inlet, the variation of the critical temperature over a 2” wafer was reduced to <25 %. Measurements of a 132-pixel KID array from these films reveal a sensitivity of 16 ...

Oral Contribution
We report on the development of microwave kinetic inductance detectors (MKIDs) for the ultra-violet, optical, and near-IR (UVOIR) wavelength regime. UVOIR MKIDs have been rapidly evolving in terms of resonator geometry, array size, and even choice of superconductor material. We detail this recent history of UVOIR MKID development and examine the detector design goals and challenges put forth...

Oral Contribution
The goal of the CALDER (Cryogenic wide-Area Light Detectors with Excellent Resolution) project is the development of light detectors with large active area and noise energy resolution smaller than 20 eV RMS using phonon-mediated Kinetic Inductance Detectors (KIDs). The detectors are developed to improve the background suppression in large-mass bolometric experiments such as CUORE, via the...

Oral Contribution
One aspect of state of the art superconducting circuits are low loss inductive elements, e.g. for resonators or qubit loop inductances.
We present a novel approach for compact and high quality microwave circuits using thin film wires made from superconducting aluminium-oxide. Due to the nano-scale grain size, the material was mostly investigated with the focus on the intrinsic granularity and...
