[8a-A409-8] Observation of Edge States in Nanoscale Topological Photonic Crystals

Topological photonics is a burgeoning subfield of optics, inspired by the discovery of topological insulators in condensed matter. A striking feature of such materials is the existence of edge modes robust against disorder. Such modes are particularly attractive for chip-scale nanophotonic systems for telecommunications. Another appeal is that directional edge states can be interfaced with quantum emitters to realize novel many-body systems such as the fractional quantum Hall state. Building upon previous work, we present a new design for an all-dielectric nanoscale topological photonic crystal and present experimental results consistent with the existence of edge states.
