Description
We propose to bandgap-engineer the antimony-based Group III-V compound semiconductor 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 (LWIR) 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 re-design the basic LWIR SLS photodiode to significantly increase quantum efficiency over the current state-of-the-art while minimizing dark current. Phase II will use this breakthrough to develop a longwave/longwave dualband infrared FPA with the high quantum efficiency and low spectral crosstalk. We will also engage with a Systems Prime in Phase II to package the FPA for a systems level test following Phase II. Approved for Public Release 14-MDA-8047 (14 Nov 14)
