Characterization of Mid-Infrared Intersubband Detectors for Astronomical Heterodyne Interferometry

Tituan Allain, Mohammadreza Saemian, Carlo Sirtori +1

One of the major challenges of mid-infrared astronomical heterodyne interferometry is its sensitivity limitations. Detectors capable of handling several 10 GHz bandwidths have been…
