New photonic platform offers a four-lane highway for light
Topological photonics can force propagating light to travel in a single direction—allowing 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 engineer...

Topological photonics can force propagating light to travel in a single direction—allowing 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 "topological insulator" regions, leaving most of the material unavailable for light transport.
