Photon upconversion: Steering light with supercritical coupling

National University of Singapore researchers and their collaborators have unveiled a novel concept termed "supercritical coupling" that enables a several-fold increase in photon upconversion efficiency. This discovery not ...

Image denoising using a diffractive material

While image denoising algorithms have undergone extensive research and advancements in the past decades, classical denoising techniques often necessitate numerous iterations for their inference, making them less suitable ...
