Scientists illuminate secrets of a nanomaterial that is both twisted and untwisted at the same time. The material developed at University of Bath allows for…
Many natural and synthetic chemical systems react and change their properties in the presence of certain kinds of light. These reactions can occur too quickly…
JILA physicists have demonstrated a novel atomic clock design that combines near-continuous operation with strong signals and high stability, features not previously found together in…
Optical waves propagating away from a point source typically exhibit circular (convex) wavefronts. “Like waves on a water surface when a stone is dropped,” explains…
Researchers have designed a new LED-based train headlight that uses a tenth of the energy required for headlights using conventional light sources. If operated 8…
Brightly colored Australian peacock spiders (Maratus spp.) captivate even the most arachnophobic viewers with their flamboyant courtship displays featuring diverse and intricate body colorations, patterns,…
New research from MIT reveals a practical way to introduce second-order nonlinearities into silicon photonics, showing that silicon can reproduce physical phenomena exploited by high-end…
A team of scientists from the Max Planck Institute for the Science of Light in Erlangen has discovered a new mechanism for guiding light in…
Using ultrafast laser flashes, physicists from the Max Planck Institute have generated the fastest electric current that has ever been measured inside a solid material….
A new study from MIT shows that some “forbidden” light emissions are in fact possible, and could enable new sensors and light-emitting devices. A new…
Scientists have now developed a universal quantum gate, which could become the key component in a quantum computer. Light particles completely ignore each other. In…
While the Rochester Cloak relied solely on lenses, a newly developed system combines a different type of lens array combined with a digital scanning and…
Researchers from the Laboratory for Attosecond Physics generated for the first time visible flashes of light in attosecond dimensions. They dispatched the light-flashes to electrons…
A new imaging system developed at the MIT Media Lab uses an open-ended bundle of optical fibers — no lenses, or protective housing needed. The…
Physicists outline a new concept called the “exceptional ring.” Optics research just got a bit more exceptional, and the world may benefit. Physicists have long…
A team of engineers from UC San Diego have developed a new design for a cloaking device that overcomes some of the limitations of existing…
Using a new algorithm, engineers from Stanford University have developed a prism-like device that can split a beam of light into different colors and bend…
