Abstract

One of the major goals of modern astronomy is the atmospheric characterization of small exoplanets to learn about their diversity, habitability and ultimately, whether they harbor life. The Large Interferometer For Exoplanets initiative aims to perform atmospheric characterization of these planets in the mid-infrared (MIR) wavelength regime (4 to 18.5 micron). Extremely sensitive and highly efficient detectors are required to detect the faint signal from these small exoplanets. Kinetic Inductance Detectors (KIDs) are a promising candidate as they are able to count single photons with no readout noise or dark current. In this work we experimentally show that KIDs are able to do photon counting at 4 wavelengths between 3.8 and 24 micron. We also compare the performance of two KID designs to investigate what design would be optimal across the MIR band.
