Abstract

We present modeling of distributed λ /4 microwave kinetic inductance detectors (MKIDs) showing how electromagnetic cross coupling between the MKID resonators can occur at frequencies corresponding to the microwave readout signal (∼ 4–8 GHz). We then show system beam pattern measurements in the reimaged focal plane of a 72 detector array of lens–antenna coupled MKIDs at 850 GHz, which enables a direct measure of any residual optical crosstalk. With use of transmission line bridges we see no residual cross coupling between MKIDs and hence low crosstalk down to the − 30 dB level, with near Gaussian shape (limited by reimaging optics) to − 10 dB level.
