Abstract

We report experiments and modeling of surface plasmon resonance (SPR)-assisted coupling to whispering-gallery modes in dielectric microresonators. Our experiments use a gold-coated glass-prism that is evanescently coupled to a 125 - μ m -diameter silica-micropillar resonator. We find nearly 12-fold enhancement in the whispering-gallery resonance extinction ratio in the vicinity of the SPR angle using a 50 - nm gold-film. The measured trends of the enhancement, as a function of the laser-beam incident angle and the gold-film thickness, show good qualitative agreement with our modeling of SPR-assisted coupling to ring resonator modes. Our modeling suggests that the far-field interference between the SPR-enhanced microresonator mode field and the attenuated total internal reflected field from the prism gives the observed extinction ratio enhancement.
