Strained layer superlattice focal plane array maturation for computational imaging applications

Anduril Industries is maturing strained layer superlattice (SLS) focal planes for application in computational pixel imager (CPI) systems. The CPI architecture uses an advanced digital pixel readout integrated circuit (ROIC) that has been developed over the last twenty years and offers several benefits for advanced imaging applications. This technology paired with SLS infrared detector arrays provide a high performance and cost-effective approach for a new generation of infrared imaging products. This paper will discuss the maturation of long-wavelength infrared (LWIR) SLS detector designs to achieve high quantum efficiency (> 50%) and low dark current (1x Rule-07) in varying focal plane array formats and pixel sizes for product application. We will also review the extension of our approach to spectral bands that include mid-wavelength infrared (MWIR) and dual-band mid-wavelength infrared / long-wavelength infrared (M/LWIR).
