Nano Antennas for Data Transfer

Let there be light – and it was directional: The world’s first electrically powered Yagi-Uda antenna was built at the University of Würzburg’s Department of Physics. (Picture: Department of Physics) (Image: Physikalisches Institut

For the first time, physicists have successfully converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in size.

Directional antennas convert electrical signals to radio waves and emit them in a particular direction, allowing increased performance and reduced interference. This principle, which is useful in radio wave technology, could also be interesting for miniaturised light sources...
