Purcell-Enhanced, Directional Light-Matter Interaction in a Waveguide-Coupled Nanocavity

Nicholas J. Martin, Dominic Hallett, Mateusz Duda +9

We demonstrate electrically tunable, spin-dependent, directional coupling of single photons by embedding quantum dots (QDs) in a waveguide-coupled nanocavity. The directional behav…
