Future generation of astronomical imaging spectrometers are targeting the far
infrared wavelengths to close the THz astronomy gap. Similar to lens antenna
coupled Microwave Kinetic Inductance Detectors (MKIDs), lens absorber coupled
MKIDs are a candidate for highly sensitive large format detector arrays.
However, the latter is more robust to misalignment and assembly issues at THz
frequencies due to its incoherent detection mechanism while requiring a less
complex fabrication process. In this work, the performance of such detectors is
investigated. The fabrication and sensitivity measurement of several lens
absorber coupled MKID array prototypes operating at 6.98 and 12 THz central
frequencies is on-going.Comment: 2 pages, 2 figures, IRMMW-THz conference pape
