The coupling mechanism is based on cavity-enhanced Rayleigh scattering. Collected spectra exhibit Lorentzian dips, Fano shapes, or Lorentzian peaks, with a coupling efficiency around 13%. The spectra are characterized by the coupling gap, polarization, and fiber tip position. The coupling method is simple, low-cost and, most importantly, the Q-factor can be maintained at 10(8) over a wide coupling range, thereby making it suitable for metrology, sensing, or cavity quantum electrodynamics experiments.}, pages = {3386--3389}, title = {Excitation of whispering gallery modes with a “point-and-play,” fiber-based, optical nano-antenna}, volume = {44}, year = {2019} }
