Paper Abstract

We present the performance of longwave infrared focal plane arrays (FPAs) made from Type-II InAs/GaSb strained layer superlattice (SLS) photodiodes. In 320x256 FPAs operating at 77K, we measure cutoff wavelength ~ 8.5 μm, dark current density ~ 10-5 A/cm2, quantum efficiency > 5% (with 2 μm -thick absorber photodiode), and pixel operability ~ 96%. Device physics and FPA performance are graphed. Current challenges are discussed.
