Abstract

An InAs/GaSb type-II superlattice-based mid-wavelength infrared (MWIR) 320 × 256 unipolar focal plane array (FPA) using pMp architecture exhibited excellent infrared image from 81 to 150 K and ∼98% operability, which illustrated the possibility for high operation temperature application. At 150 K and ?50 mV operation bias, the 27 μm pixels exhibited dark current density to be 1.2 × 10?⁵ A?cm², with 50% cutoff wavelength of 4.9 μm, quantum efficiency of 67% at peak responsivity (4.6 μm), and specific detectivity of 1.2 × 10¹² Jones. At 90 K and below, the 27 μm pixels exhibited system limited dark current density, which is below 1 × 10^?9 A?cm², and specific detectivity of 1.5 × 10¹⁴ Jones. From 81 to 100 K, the FPA showed ∼11 mK NEDT by using F/2.3 optics and a 9.69 ms integration time.
