Stanford University researchers have developed a laser-based system that can reproduce images of objects hidden from view. The technology can be used to enhance the safety of self-driving vehicles, as well as applied to serve other functions.
Physicists at the University of Texas at Austin and City University of New York have developed a fully passive isolator consisting of coupled nonlinear resonators to propagate microwaves over a broad bandwidth. The design could be transferred to optical applications, as well.
Laser beams could wirelessly charge newer smartphones just as quickly as a cumbersome USB cables or charging pads, according to researchers at the University of Washington (UW). The team claims to be the first to design and demonstrate a novel, laser-based wireless power delivery system with built-in safety features for personal or commercial use.
The U.S. Missile Defense Agency (MDA) is proposing to spend $66 million on a program to develop and deploy unmanned aerial vehicles (UAV) that fire lasers at intercontinental ballistic missiles (ICBMs) shortly after takeoff, or during their boost phase of flight, when they are most vulnerable.
The injector gun and first cryomodule for Linac Coherent Light Source II (LCLS-II) — one of the most advanced superconducting laser projects in the world and the only one in the U.S. — have arrived at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory in Menlo Park, California.
Scientists at Fudan University in Shanghai, China, have demonstrated the world's first optically pumped all-silicon distributed-feedback (DFB) laser, a key achievement toward realizing possibilities in integrated silicon photonics.
Physicists report the first experimental observation of accelerating light beams in curved space. This phenomenon provides new ideas for emulating Einstein's general relativity, as well as new ways of propagating light in curved surfaces and media.
Scientists at Massachusetts Institute of Technology (MIT) have observed two distinct topological effects in an open system of photonic crystals. Such phenomena open new possibilities in making novel light-based computing systems or light-emitting devices.
