Effective spin photon interface uses symmetrical waveguide in sliding surface

摘要

An optical device comprising a planar waveguide and a quantum emitter is presented. The planar waveguide comprises a longitudinal extending guiding region with a first side and a second side. A first nanostructure is arranged on the first side of the guiding region, and a second nanostructure arranged on the second side of the guiding region. The planar waveguide includes a first longitudinal region where the first nanostructure and the second structure are arranged substantially glide-plane symmetric about the guiding region of the planar waveguide, and the quantum emitter is coupled to the first longitudinal region of the planar waveguide.
