Pyramid nanoscale antennas beam light up and down

Wednesday, December 17, 2014 - 05:30 in Physics & Chemistry

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 published their results online on 12 December 2014 in Physical Review Letters.
