Liquid light switch could enable more powerful electronics

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 ...

Nanoscale one-way street for light

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.

Applications of optical fibre for sensors

Mikel Bravo-Acha's PhD thesis has focused on the applications of optical fibre as a sensor. In the course of his research, conducted at the NUP/UPNA-Public University of Navarre, he monitored a sensor fitted to optical fibre ...

Photonics to revolutionise internet speeds

While people may have never heard of photonics before, they will surely have heard about the technology that relies on its existence, namely the internet, computers and smartphones.
