Nanoimaging of topologically protected waveguide mode at telecommunication frequency
Nanoimaging of topologically protected waveguide mode at telecommunication frequency
We demonstrate near-field mapping of a valley-Hall photonic waveguide at telecommunication frequency. Launching and guiding of an optical mode along the boundary between opposite valley-Chern-index domains is experimentally observed in real space, in agreement with theoretical calculations.

Abstract
We demonstrate near-field mapping of a valley-Hall photonic waveguide at telecommunication frequency. Launching and guiding of an optical mode along the boundary between opposite valley-Chern-index domains is experimentally observed in real space, in agreement with theoretical calculations.
