Paper Abstract

Raytheon has developed SWIR and Visible-SWIR Focal Plane Arrays (FPAs) with over one million pixels that meet the demanding requirements of astronomy, night vision, and other low background systems. FPA formats are 1280 × 1024, 1024 × 1024 and 2048 × 2048, with detector elements on 20 μm pitch. This paper describes recent results on SWIR HgCdTe detectors, low-noise Readout Integrated Circuits (ROICs), and FPA imaging. SWIR HgCdTe detectors have been fabricated with cutoff wavelengths of 1.7 and 2.5 μm and have demonstrated high quantum efficiency and flat spectrals, including visible response to 400 nm. We compare InGaAs and HgCdTe detectors, and show HgCdTe passivation improvements which increase carrier lifetime fourfold over existing processes
