On-Chip Topological Light

August 4, 2014 11:04 am | by Joint Quantum Institute | Comments

Topological transport of light is the photonic analog of topological electron flow in certain semiconductors. In the electron case, the current flows around the edge of the material but not through the bulk. It is "topological" in that even if electrons encounter impurities in the material the electrons will continue to flow without losing energy.
