Recently, the research team of Dong Hongxing and Zhang Long from the Research Center of Infrared Optical Materials of the Chinese Academy of Sciences Shanghai Institute of Optics and Precision Mechanics, in cooperation with Huazhong University of Science and Technology, reported a new mechanism for generating dynamically tunable single-mode lasers from exciton polaritons with ultra-low thresholds,...
Introduction and application of a micro optical platform using metasurfacesMetasurfaces are artificial materials that excel in manipulating perception. Due to the fact that metasurfaces can reduce the size of lenses to one thousandth of traditional lenses, they have attracted great attention as optical components for miniaturization of next-generation virtual reality, augmented reality, and LiDAR ...
