This $287,836 Project Grant from the National Science Foundation's Division of Electrical, Communications and Cyber Systems under the Engineering program (CFDA 47.041) will fund the development of a highly compact mid-infrared spectrometer based on a single, tunable van der Waals heterostructure photodetector at Yale University from October 1, 2022 to September 30, 2025. The research aims to advance on-chip mid-infrared spectroscopy through investigating light-matter interactions in emerging materials, fabricating tunable photodetectors, and developing algorithms to demonstrate spectroscopic functionality within a footprint comparable to the operational wavelength. This builds upon a novel tunable single-element detection scheme and leverages properties of van der Waals heterostructures to overcome resolution limitations of traditional on-chip spectrometers.
