Researchers Develop a Novel Approach to Design, Fabricate Thin-Film Infrared Light Sources

Vanderbilt and Penn State engineers have developed a novel approach to design and fabricate thin-film infrared light sources with near-arbitrary spectral output driven by heat, along with a machine learning methodology called inverse design that reduced the optimization time for these devices from weeks or months on a multi-core computer to a few minutes on a consumer-grade desktop.
