Light sail technology is a fascinating concept and a step change in rocket propulsion. It may not be big and impressive like the Saturn V, the Space Shuttle or the new Starship rocket but when it comes to traveling among ...
In recent decades, augmented reality (AR) has evolved from a futuristic concept to a tangible and pervasive technology. AR enhances our perception and interaction with the environment by seamlessly blending projected virtual ...
Chirality is an intrinsic property of an object that cannot coincide with its mirror image by translation or rotation. In order to realize strong chiral light-matter interactions which are usually weak in natural materials ...
Optical beams carrying orbital angular momentum (OAM) attract widespread attention and play an important role in optical data storage, optical communications, quantum information processing, super-resolution imaging, and ...
The holographic 3D display is an important technology with excellent application prospects. However, the viewing angle of holographic 3D displays is currently limited by existing strategies. This significant challenge must ...
Non-Hermitian systems have numerous alluring optical properties at exceptional points (EPs) and have attracted extensive attention because of their great prospects in applications such as optical sensing, integrated optics, ...
Polarimetric imaging can uncover features invisible to human eyes and conventional imaging sensors, and it is becoming an ever more essential technique in modern society. Conventional polarimetric imaging systems require ...
Lanthanide-doped upconversion nanoparticles (UCNPs) demonstrate many superior properties of broadly-tunable multicolor emission and long emission lifetimes. This makes them well-suited for many light-emission applications. ...
A new nanoscience study led by a researcher at the Department of Energy's Oak Ridge National Laboratory takes a big-picture look at how scientists study materials at the smallest scales.
Metasurfaces are artificial materials adept at manipulating perception. With metasurfaces allowing lenses to be reduced to one 10,000th the size of conventional lenses, they are generating considerable interest as optical ...
