Interaction of a microresonator with a nanoscatterer

We present a theoretical analysis of the effects induced on the high-Q whispering-gallery modes of a microsphere resonator by a small metallic scatterer. We study the near-field tip-microsphere interaction varying the distance between the two spheres, in correspondence of the most perturbed modes of the microsphere. The obtained results show that this kind of interaction can be used to achieve an active control of whispering gallery resonances.
