In the past few years, optical atomic clocks have made spectacular progress, becoming 100 times more precise than the best caesium clocks. So far, their precision has been available only locally, since frequency transfer ...
Researchers have built a miniature electro-optical switch which can change the spin—or angular momentum—of a liquid form of light by applying electric fields to a semiconductor device a millionth of a metre in size. Their ...
Scientists have opened a door to faster, cheaper telecommunications after proving a new link between silicon chips and 'rare-earth' metals used in internet signalling.
An optical device at nanoscale which allows light to pass in only one direction has been developed at TU Wien (Vienna). It consists of alkali atoms which are coupled to ultrathin glass fibres.
A team of researchers, including The University of Queensland's Dr Joel Carpenter, has developed echo-less lights that could improve medical imaging inside the body, leading to less-intrusive surgery.
As hackers get more sophisticated in their cyber crime efforts, we need to look to new technology to make our systems more secure, and potentially unhackable.
A new way to process fibre optic signals has been demonstrated by UCL researchers, which could double the distance at which data travels error-free through transatlantic sub-marine cables.
Researchers from the University of Southampton have revealed a breakthrough in optical fibre communications.
(Phys.org) —University of Auckland physicist Dr Miro Erkintalo is part of an international team investigating how lasers and optical fibres can be used to understand freakishly large waves on the ocean.
Physicists at the University of Geneva have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber.
