Abstract
We propose to bandgap engineer the InAs/GaSb/AlSb material system to realize a dualband focal plane array (FPA) made up of stacked multi-barrier Type-II strained layer superlattice (SLS) photodiodes. Two longwave infrared spectral bands will be imaged in alternate frames by using a readout multiplexer that flips the voltage bias across the FPA from frame to frame. In Phase I, we will develop and demonstrate the basic dualband sensor, which will be converted into a proof-of-concept 320x256 dualband FPA in the Phase I Option. Phase II will develop a 640x512 version with the goal of high (single band level) performance in each of the two longwave bands combined with low spectral crosstalk. We will also engage with a Systems Prime in Phase II so as to ready the FPA and packaging for a systems level test following Phase II.
