Nanoparticles and microspheres: tools to study the interaction of quantum emitters via shared optical modes

In: Laser Resonators and Beam Control VI, vol. 5333(1), pp. 174-182, SPIE. Proc. of SPIE.

In this paper we discuss different configurations of experiments where two nanoemitters are coupled through exchange of photons via shared cavity modes. We introduce an experimental setup where we combine microspheres as optical resonators with the techniques of scanning confocal and scanning near-field microscopy. The emission of fluorescence light from a single nanoemitter in high-Q whispering-gallery modes is demonstrated. Also first experiments with a novel type of stable active nanoprobe are reported. These results demonstrate the feasibility of experiments where optical modes mediate interactions between few quantum emitters in a controlled manner.
