Abstract

We design and experimentally demonstrate silicon-based topological valley-Hall photonic crystals, that are compatible with current semiconductor technologies and operate at near-infrared frequencies. Robust and reflection-less light propagation around sharp turns is demonstrated both theoretically and experimentally. This work is an important step towards integrated topological photonics.
