Abstract

This paper investigates arrays of HgCdTe photon trapping detectors. Performance of volume reduced single mesas is compared to volume reduced photon trap detectors. Good agreement with model trends is observed. Photon trap detectors exhibit improved performance compared to single mesas, with measured noise equivalent temperature difference (NEDT) of 40 mK and 100 mK at temperatures of 180 K and 200 K, with good operability. Performance as a function of temperature has also been investigated.
