Chiral quantum optics goes electric

The local polarization of light in nanophotonic waveguides changes with the light's direction of propagation. By electrically controlling the polarization of optically created waveguide-coupled excitons in a two-dimensional semiconductor, researchers demonstrate voltage-controlled routing of photons in an integrated nanophotonic device.
