Physical Review A 80(1): 1-4.0556-2791http://nrs.harvard.edu/urn-3:HUL.InstRepos:3409103We demonstrate that a slot waveguide provides a broadband loss-free platform suitable for applications in quantum optics. We find that strong coupling between light quanta and a single quantum emitter placed in the waveguide slot can be achieved with efficiency higher than 96% and Purcell factor (spontaneous emission factor) larger than 200. The proposed system is a promising platform for quantum information processing and can be used to realize an efficient single photon source and optically addressable photon register.en-USoptical information processingoptical waveguidesquantum electrodynamicsquantum opticsspontaneous emissionJournal Article2009-11-1610.1103/PhysRevA.80.011810
