Design Considerations

We report the design, fabrication, and testing of lumped element kinetic inductance detectors (LEKID) showing performance in line with the requirements of the next generation space telescopes operating in the spectral range from 80 GHz to 600 GHz. This range is of particular interest for cosmic microwave background studies. For this purpose we designed and fabricated 100 pixel arrays covering five distinct bands. These wafers were measured via multiplexing, in which a full array is read out using a single pair of lines. We adopted a custom cold black body installed in front of the detectors and regulated at temperatures between 1 K and 20 K. In this paper, we describe in the main design considerations, fabrication processes, testing and data analysis.

Abstract Arrays of lumped-element kinetic inductance detectors (LEKIDs) optically coupled through an antenna-coupled transmission line are a promising candidate for future cosmic microwave background experiments. However, the dielectric materials used for the microstrip architecture are known to degrade the performance of superconducting resonators. In this paper, we investigate the feasibility of microstrip coupling to a LEKID, focusing on a systematic study of the effect of depositing amorphous silicon nitride on a LEKID. The discrete and spatially separated inductive and capacitive regions of the LEKID allow us to vary the degree of dielectric coverage and determine the limitations of the microstrip coupling architecture. We show that by careful removal of dielectric from regions of high electric field in the capacitor, there is minimal degradation in dielectric loss tangent of a partially covered lumped-element resonator. We present the effects on the resonant frequency and noise power spectral density and, using the dark responsivity, provide an estimate for the resulting detector sensitivity.

Astronomical Observations

Kinetic inductance detectors (KIDs) have a lot of potential in the field of astronomical observations; they are easy to fabricate and are highly multiplexible. KIDs can be as simple as a single lithographic layer and 1000s of them can be read out on a single line. Future observations of the cosmic microwave background (CMB) will require huge pixel count detector arrays and KIDs are able to fill this role promisingly. This paper primarily discusses the design and simulation of KIDs in Sonnet to be used in a polarimeter chip intended for observation of the polarization anisotropy of the CMB. Both background information of the CMB and KID theory will be reviewed.
