This research develops nanostructured optical devices that dramatically improve camera efficiency by redirecting light rather than discarding unwanted wavelengths. Using nanoscale patterned glass inspired by semiconductor fabrication techniques, the work could produce mobile cameras with significantly better low-light performance, higher image quality, faster imaging, and improved efficiency at ultra-high resolutions.

This research develops cavity-based methods for controlling thermal radiation by transforming random heat emission into coherent, directional thermal beams. Unlike traditional narrowband approaches, the technique enables broadband heat control using practical materials such as silicon and germanium, with potential applications in energy efficiency, waste-heat recycling, cooling technologies, and climate mitigation.
