Abstract

We measured the coupling of the florescence from semiconductor nano-crystals and sub-micron sized dye-doped beads to high-Q whispering gallery modes (WGM) of a microsphere resonator. With Q-factors as high as 109 the florescence could be extracted in a controlled way via a prism coupler. We observed nearly 100 % modulation in the spectrum which reflects the coupling to the WGMs. With the help of a beam scanning confocal microscope we were able to address a single 500 nm sized dye-doped bead on the sphere’s surface and to collect and analyze its florescence in a well defined manner via the prism coupler.
