Topological physics has introduced a modern design principle in optics, providing build-in protection to specific types of disorder. This work demonstrates how such principles could be used to create a topological resonator in nanophotonic crystals so as to enable chiral light-matter interaction in the context of cavity quantum electrodynamics. A moderate Purcell effect is shown as an experimental proof of principle.
