Large Area Substrates Provide a Path to Practical Devices
Research on Type II Superlattice (T2SL) FPAs is increasing rapidly as evidenced by the ten papers presented on these detectors at the April SPIE Infrared Technology & Applications Conference in Orlando. Currently, most of this work is aimed at improving performance in the LWIR, since good performance has already been demonstrated in the MWIR.
Type II Superlattice (T2SL) FPAs have made great progress over the last three years. Some are even heralding these detectors as the successor to mercury cadmium telluride.
