Abstract

In principle, a microspherical resonator pendulum can be trapped using the optical forces produced by two simultaneously excited whispering gallery modes of a photonic molecule, comprising two microspherical cavities. The cavity-enhanced optical force generated in the photonic molecule creates an optomechanical potential that can trap the pendulum at an equilibrium position by carefully choosing the excitation laser frequencies. In this paper, we study the mechanical characteristics of microsphere pendulums by evanescently detecting the pendulum motion. Nonlinear effects like electromagnetically induced transparency and absorption, and Fano resonances have also been observed using a microsphere-fiber taper system and the results are presented here.
