Development Status Of T2sl Infrared Detector In Jaxa

We present the development status of Type II superlattice infrared detector (T2SL) for future space applications in JAXA. Space-borne infrared detectors require higher sensitivity, higher resolution, and larger formats than ground-based infrared detectors. The Geostationary Earth observation satellite is one of mission candidates to adopt T2SL for infrared sensor. In order to meet more demanding for such mission requirements, JAXA has developed T2SL. T2SL has preferable characteristics in terms of operating temperature and spectral sensityivity in the range of near infrared to very long wavelength infrared region.In this presentation, we report the development history of T2SL focal plane array in JAXA.
