On-chip topological light
College Park MD (SPX) Aug 05, 2014 - 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. In the photonic equivalent, light flows no ... more
