Cavity (Q)ED with microsphere resonators

Proceedings of SPIE, 6872:68720R.

In this paper, we review experiments performed with silica microspheres as optical resonators. We introduce our approach to utilize scanning optical near-field probes as nano scatterers and nano emitters. Applications of mode mapping techniques to improve selective coupling to high-Q modes and to study Raman lasing are presented. Furthermore, we analyze the emission properties of a single nano emitter interacting with resonator modes and demonstrate long-distance energy transfer between two nano emitters. The controlled splitting of a high-Q mode by a single Rayleigh scatterer is also demonstrated.
