Over the next 5 years, we will pursue an aggressive research program on advanced photodetectors and imagers targeted to emerging applications in health and environmental sciences. This research will significantly extend our research expertise and leading-edge results to model, design, fabricate and characterize low-cost photodetectors and imagers that use innovative device designs, circuits and systems, as well as emerging photodetector structures in compound semiconductor materials. We will leverage our research expertise in photodetector design and integrated circuits to create fully integrated silicon-based and hybrid compound semiconductor-based optical detection systems for low-cost, miniaturized biomedical and environmental analytical systems. Our proposed research will be, - Modeling and optimized design of "foundry-based" high-performance, photodetectors, pixels, digital integrated circuits and integrated imagers for applications including early disease detection using positron emission tomography, functional brain imaging or fluorescent lifetime imaging, and water quality monitoring using time-gated Raman spectroscopy; - Mitigation of challenging issues that degrade the performance of advanced photodetectors and imagers such as noise, afterpulsing, jitter or timing resolution; and - Accurate, calibrated models to predict the static and dynamic characteristics of advanced quantum dot infrared photodetector structures, and their optimized design and fabrication for mid-infrared biological and chemical sensing applications.
