Twisting the light away using ultrasmall holes

A new study shows that light transmitted through apertures smaller than the wavelength of light go through a radical change, splitting into two symmetrical counter-rotating polarisations.

Spin lasers facilitate rapid data transfer

Engineers at Ruhr-Universität Bochum have developed a novel concept for rapid data transfer via optical fibre cables. In current systems, a laser transmits light signals through the cables and information is coded in the ...

Dissecting a stellar explosion

(PhysOrg.com) -- Integral has captured one of the brightest gamma-ray bursts ever seen. A meticulous analysis of the data has allowed astronomers to investigate the initial phases of this giant stellar explosion, which led ...

Research to probe deep within a solar cell

Engineers and scientists from the University of Sheffield have pioneered a new technique to analyse PCBM, a material used in polymer photovoltaic cells, obtaining details of the structure of the material which will be vital ...

New remote control for molecular motors

In the eyes of physicists, magnetic molecules can be considered as nanoscale magnets. Remotely controlling the direction in which they rotate, like spinning tops, may intuitively be difficult to achieve. However, Russian ...
