Photon upconversion: Steering light with supercritical coupling
Researchers from the National University of Singapore (NUS) have unveiled a novel concept termed “supercritical coupling” that enables several folds increase in photon upconversion efficiency. This discovery not only challenges existing paradigms, but also opens a new direction in the control of light emission. Photon upconversion, the process of converting low-energy photons into higher-energy ones, … Read more
