SK Infrared LLC, a spin-off from the Krishna INfrared Detector (KIND) laboratory at the UNM ( is proposing to develop a dual band SLS based imager using an nBn based heterostructure design in collaboration with Raytheon Vision Systems (letter attached). The proposed effort leverages the technical expertise and facilities of only one of the two university laboratories in the world that has demonstrated "Epi to Camera" research. The Krishna group has a successful track record in the design, growth, fabrication and characterization of SLS FPAs. UNM has agreed to let SK Infrared LLC use the facilities at CHTM (letter attached) for this effort. This will include access to a brand-new VEECO Gen-10 MBE reactor. The Krishna group has demonstrated the first SLS based nBn single pixel detector and 320x256 focal plane arrays with an NETD=24mK. Moreover, by engineering the bandgaps of the absorber on either side of the barrier, the Krishna group has demonstrated a dual band nBn detector. Prof. Krishna also has close ties with DoD agencies such as Army Night Vision Laboratory and is a part of the user group that provides feedback to FLIR for the new dual polarity ROIC as a part of MDA''S FastFPA program
