Summary: | We design photonic crystal waveguides with efficient chiral light-matter interfaces that can be integrated with solid-state quantum emitters. By using glide-plane-symmetric waveguides, we show that chiral light-matter interaction can exist even in the presence of slow light with slowdown factors of up to 100 and therefore the light-matter interaction exhibits both strong Purcell enhancement and chirality. This allows for near-unity directional [beta]-factors for a range of emitter positions and frequencies. Additionally, we design an efficient mode adapter to couple light from a standard nanobeam waveguide to the glide-plane symmetric photonic crystal waveguide. Our work sets the stage for performing future experiments on a solid-state platform. |
