Abstract

High resolution multi-band infrared detection of terrestrial objects is useful in applications such as long range and high altitude surveillance. In this paper, we present a 640 by 512 type-II superlattice focal plane array (FPA) in the long-wave infrared (LWIR) suitable for such purposes, featuring 100% cutoff wavelengths at 9.5μm (blue channel) and 13μm (red). The dual band camera is single-bump hybridized to an Indigo 30μm pitch ISC0905 read-out integrated circuit. Test pixels revealed background limited behavior with specific detectivities as high as ∼5x10 ¹¹ Jones at 7.9μm (blue) and ∼1x10 ¹¹ Jones at 10.2μm (red) at 77K.
