Researchers from FOM Institute AMOLF and Philips Research have designed and fabricated a new type of nanoscale antenna. The new antennas look like pyramids, rather than the more commonly used straight pillars. The pyramid shape enhances the interference between the magnetic and electric fields of light. This makes the pyramid-shaped antenna capable of enhancing light emission and beaming different colours of light towards opposite directions. This finding could lead to more efficient light emitting devices (LEDs). The researchers publish their results online on 12 December 2014 in Physical Review Letters
Researchers from FOM institute AMOLF have discovered what determines the accuracy with which cells can measure chemical concentrations. They described the results of their research in two publications: on 24 November online in the Proceedings of the National Academy of Sciences and on 16 December in Physical Review Letters.
Researchers TU/e and FOM obtain vital control on the emission of photons.
In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a 'quantum internet'. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum internet is control of the shape of these photons. Researchers at Eindhoven University of Technology (TU/e) and the FOM foundation have now succeeded for the first time in getting this control within the required short time. These findings are published Monday 15 december in Nature Communications.
