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.

If light is able to propagate from left to right, the opposite direction is usually allowed as well. A beam of light can…
