State Key Lab for Mesoscopic Physics, Department of Physics, Peking University, P. R. China(Dated: June 13, 2012)We propose a hybrid photonic-plasmonic resonant structure which consists of a metal nanoparticle(MNP) and a whispering gallery mode (WGM) microcavity. It is found that the hybrid mode enablesa strong interaction between the light and matter, and the single-atom cooperativity is enhanced bymore than two orders of magnitude compared to that in a bare WGM microcavity. This remarkableimprovement originates from two aspects: (1) the MNP offers a highly enhanced local field in thevicinity of an emitter, and (2), surprisingly, the high-Q property of WGMs can be maintained inthe presence of the MNP. Thus the present system has great advantages over a single microcavityor a single MNP, and holds great potential in quantum optics, nonlinear optics and highly sensitivebiosening.
