Abstract
We propose and experimentally demonstrate an alternative WGR coupling scheme that is easy to make, requires little alignment, and is both convenient and stable with no need for phase matching. It relies on cavity enhanced Rayleigh scattering. This is the first, single-ended, fiber-based optical nano-antenna that can be used to simultaneously excite and collect light from the WGMs of a microresonator, coupling efficiency as high as 13% is observed, making it very promising for optical sensing applications or cQED.
