Abstract

Midwave infrared (MWIR) type-II superlattices (T2SL) have revolutionized the market with possibility of low Size, Weight and Power (SWaP) detectors. IRnova currently has a full-scale production of SWaP T2SL detectors (Oden MW, 640×512 on 15μm pitch), which have demonstrated excellent performance for operating temperatures up to 110 K at F/5.5. Development of high-resolution detectors with small pixel pitch (HD, 1280×1024 pixels) for MWIR as well as long wave and very long wave infrared (LWIR/VLWIR) detection is currently ongoing. In this paper, it has been demonstrated that the low dark current density and high sensitivity needed for high operating temperatures are maintained also for these small pixel pitch detectors, which makes IRnova’s T2SL technology fully compatible with next generation HD detectors.
