Abstract

We investigate whispering-gallery-like surface plasmon modes in a silver nanoring located on a diamond substrate. These hybrid modes are demonstrated to possess not only high quality factors (several hundred), but also ultra-small mode area as well as ultra-small mode volume (less than 0.1μm3). In experiments, this cavity structure shows great potential for studying a strong and deterministic coherent interaction between the hybrid mode and single quantum system embedded in the substrate.
