Researchers switch a quantum light source in a superfast way

Scientists from the FOM Foundation, the University of Twente and at the Institute for Nanoscience and Cryogenics in France have shown that light sources which usually emit light randomly can be coaxed to emit an ultrashort ...

Bubbles are the new lenses for nanoscale light beams

Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for next-generation, ...

Quantum cryptography goes maintream

(Phys.org)—Researchers from Toshiba and the Department of Engineering have perfected a technique that offers a less expensive way to ensure the security of high-speed fibre-optic cables, protecting communication networks ...

Training light to cool the material it strikes

(Phys.org)—Light might one day be used to cool the materials through which it passes, instead of heating them, thanks to a breakthrough by engineers at Lehigh and Johns Hopkins Universities.

Li-Fi: Edinburgh prof seeds LEDs for communication

(Phys.org)—"We believe wireless communications should be as reliable as lighting." That is a company motto of startup PureVLC (Visible Light Communication), which aims to connect the two—communications and light. They ...
