Coherent steering of nonlinear chiral valley photons with a synthetic Au–WS2 metasurfaceCoherent steering of nonlinear chiral valley photons with a synthetic Au–WS₂ metasurface, Published online: 01 April 2019; doi:10.1038/s41566-019-0399-1By entangling the phase and spin of light, a synthetic metasurface is shown to be able to coherently manipulate the valley-exciton-locked chiral emission in monolayer tungsten disulfide at room temperature. The findings will be of benefit to advanced room-temperature and free-space nonlinear, quantum and valleytronic nanodevices.
