Abstract

Topological photonics [1] is a burgeoning field of photonics due to its potential in realizing robust propagation of light for chip-scale optical communications [2] as well as novel phenomena such as fractional quantum Hall states by engineering the photonic edge states to interact with quantum emitters [3]. Towards these goals and building upon previous work [4], we have designed an all-dielectric nanoscale photonic crystal which supports topological edge states and experimentally observed the transmission of edge states near 1500 nm.
