Abstract

We demonstrate theoretically that plane wave propagating in free space can be used to excite the whispering gallery mode in dielectric microresonators grown on the top of nanoplasmonic structures, with the assistance of surface plasmon wave. We have demonstrated the coupling modes using both localized and propagating surface plasmon-supporting nanostructure surfaces.
