摘要

InAs/InAsSb type-II strained layer superlattice high-operating temperature barrier infrared detector (HOT-BIRD) focal plane arrays (FPAs) were fabricated for mid-wavelength infrared hyperspectral imaging applications on the CubeSat Infrared Atmospheric Sounder (CIRAS). At 115 K, a

$5.4 ~\mu \text{m}$

cutoff FPA demonstrated a mean quantum efficiency of 53% in the 3-

$5 ~\mu \text{m}$

band, and a mean dark current density of

$1.7\,\,\times10$

⁻⁷ A/cm ² . The mean noise equivalent differential temperature (NEDT) is 22.9 mK for 300 K background and f/7.8 optics, with an NEDT operability of 99.94%. The FPA meets the hyperspectral imaging requirements of CIRAS.
