Photon-Counting Microwave Kinetic Inductance Detectors (MKIDs) for High Resolution Far-Infrared Spectroscopy

Metadata Updated: May 2, 2019

We are developing ultrasensitive Microwave Kinetic Inductance Detectors (MKIDs) for high resolution far-infrared spectroscopy applications, with a long-term goal of achieving photon-counting sensitivity in low photon backgrounds. MKIDs are superconducting thin film microwave resonators made in planar transmission line circuits. These resonators experience a change in resonance frequency and quality factor when incident far-infrared power is absorbed in the inductor region of the detector. This perturbation can be observed by monitoring the resonator with a microwave tone on resonance via a microwave feedline. MKIDs are therefore intrinsically adapted for frequency multiplexing and appealing for use in next-generation kilo- to mega-pixel detector arrays.[HTML_REMOVED]We are motivated to pursue developments which will lead to MKIDs with photon-counting capability, since this provides a significant sensitivity benefit over power detection.A photon counting detector must have energy resolution less than the photon energy, a bandwidth faster than the photon arrival rate, and high efficiency. To achieve this performance, two attributes are desirable: 1) An MKID design that demonstrates the required sensitivity, and 2) the capability to produce devices whose response and noise are consistent with the model.[HTML_REMOVED]Design optimization depends on precise knowledge of materials parameters.[HTML_REMOVED]We are evaluating superconducting films with simple 1- or 2-layer MKID devices in order to characterize the key film properties which contribute to detector response and noise, and[HTML_REMOVED]determining fabrication techniques which will allow us to improve and reproduce these film properties.[HTML_REMOVED]We will implement a down-selected superconducting material into a far-IR-coupled MKID design, and fabricate and test these devices.
