New photonic platform offers a four-lane highway for light

Topological photonics can force propagating light to travel in a single directionallowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this one-way flow has only been found at the boundary between two specially engineered opological insulator regions, leaving most of the material unavailable for light transport.
