Abstract
We propose to develop a large-format 1Kx1K longwave infrared focal plane array (FPA) from Type-II InAs/(In)GaSb strained layer superlattice (SLS) photodiodes. In Phase I, we will develop small pixels with the goals of ~ 10 micron cutoff wavelength, quantum efficiency>60%, and dark current density<1e-5 A/cm^2 at 77K in a backside-illuminated FPA configuration. These metrics will be measured as a function of pixel size for different passivation schemes. Phase II will apply these developments to realize a 1Kx1K FPA. We will also develop a cost and yield model in Phase II and refine it with actual data in order to be able to predict the cost/pixel for SLS FPAs as a function of volume - a key metric for the commercial viability of both SLS technology and the horizontal business model for FPA manufacturing.
