Photonic crystal slow light waveguides in a kagome lattice

Canada Excellence Research Chairs, Government of Canada (CERC); H2020 European Research Council (ERC) (337508).Slow light photonic crystal waveguides tightly compress propagating light and increase interaction times, showing immense potential for all-optical delay and enhanced light–matter interactions. Yet, their practical application has largely been limited to moderate group index values (150, limited by our measurement resolution. The kagome-lattice waveguides are an excellent starting point for further slow light engineering in photonic crystal waveguides.PostprintPeer reviewe
