Performance of a 1/4 VGA Format Long-Wavelength Infrared Antimonides-Based Superlattice Focal Plane Array

Long-wavelength complementary barrier infrared detector (CBIRD) based on III-V material is hybridized to recently designed and fabricated 320 × 256 pixel format two-color read-out integrated circuit. The n-type CBIRD is characterized in terms of performance and thermal stability. This paper reports on the measured dark current density, noise equivalent difference temperature, quantum efficiency, responsivity, minimum resolvable difference temperature, and modulation transfer function.
