Dual Band MWIR/LWIR SLS FPA

This Phase I SBIR effort will develop dual-band mid-wavelength infrared/long-wavelength infrared (MWIR/LWIR) detector technology based on dual monolithic type-II strained-layer superlattices (SLS). The dual-band detector will operate in either MWIR or LWIR mode depending on the applied voltage bias, and will be compatible with the ROICs under development in the MDA FastFPA program. The dual-band SLS detector design will be done in collaboration with leading firms QmagiQ, Teledyne Imaging Sensors, and Raytheon Vision Systems. The epitaxial layer structures will be prepared by multi-wafer Sb-based MBE at IntelliEPI using proprietary in-situ tools to fully characterize and optimize the films. Detector fabrication and testing will be done by QmagiQ, TIS, and RVS. Building on the experience gained under the MDA FastFPA program, and iterations of growth and testing, has the potential for high-performance dual-band detector development.
