Optically tunable topological photonic structures

 · Invited

Abstract

Photonic topological insulators offer the possibility to eliminate backscattering losses and improve the efficiency of optical communication systems. We combine the properties of a planar silicon photonic crystal and the concept of topological protection to demonstrate dynamically controlled transmission in a topological photonic crystal that exhibits the valley Hall effect.
