Tiny antennas let long light waves see in infrared

(Phys.org) —University of Illinois at Urbana-Champaign researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared (IR) spectrum.

Physicists freeze motion of light for a minute

Physicists in Darmstadt have been able to stop something that has the greatest possible speed and that never really stops. We're talking about light. Already a decade ago, physicists stopped it very for a short moment. In ...

New phenomenon could lead to novel types of lasers and sensors

There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that ...

Researchers develop light transistor

TU Vienna has managed to turn the oscillation direction of beams of light – simply by applying an electrical current to a special material. This way, a transistor can be built that functions with light instead of electrical ...
