Abstract
Focal Plane Arrays for high-performance thermal imaging systems operating in the mid-infrared spectral range between 3-5 µm have been realized by type-II InAs/GaSb short-period superlattices. A fully operational 256 x 256 camera system showing a noise equivalent temperature difference below 10 mK is presented. The suitability of InAs/GaSb type-II superlattices for next generation thermal imagers is demonstrated with the first 288 x 384 dual color demonstrator camera which features a simultaneous and spatially coincident acquisition of two separate spectral regimes in the mid-infrared.
