Paper Abstract

We summarize the current state of 2-color Quantum Well Infrared Photodetector (QWIP) Focal Plane Array (FPA) technology. Our 2-color FPA architecture features 3 bumps/pixel to permit two vertically-stacked QWIPs to be separately biased and the two photocurrents to be simultaneously integrated. Pixel-registered imagery is simultaneously obtained in two spectral bands. We have successfully applied this architecture to realize 2-color FPAs in three sperate formats: LW/LW, MW/LW, and MW/MW. Fabrication and performance details are presented.
