Controlling the flow of light with a novel optical transistor

In an article appearing on Nov. 11 in the journal Science, researchers at EPFL and the Max Planck Institute of Quantum Optics announce the discovery of a method for coupling photons and mechanical vibrations that could have ...

Getting a better measure of spin with diamond

Diamonds are one of the most coveted gemstones. But while some may want the perfect diamond for its sparkle, physicists covet the right diamonds to perfect their experiments. The gem is a key component in a novel system that ...

A 'pause button' for light particles

How do you stop something that is faster than anything else, intangible and always in motion by nature? A team led by physicists Dr. Thorsten Peters and Professor Thomas Halfmann is doing the seemingly impossible: stopping ...

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.

Topological insulators: Persuading light to mix it up with matter

Researchers at MIT have succeeded in producing and measuring a coupling of photons and electrons on the surface of an unusual type of material called a topological insulator. This type of coupling had been predicted by theorists, ...

Switching light on and off - with photons

(PhysOrg.com) -- Cornell researchers have demonstrated that the passage of a light beam through an optical fiber can be controlled by just a few photons of another light beam.

Holograms set for greatness

A new technique that combines optical plates to manipulate laser light improves the quality of holograms.

A smarter way to make ultraviolet light beams

Existing coherent ultraviolet light sources are power hungry, bulky and expensive. University of Michigan researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve ...
