We demonstrate efficient coupling to the optical Whispering-Gallery (WG) modes of a fluidic resonator consisting of a droplet embedded in a liquid medium. Unlike previous experiments the droplet is not levitated in an optical or electrostatic trap and free space coupling is replaced by phase-matched, waveguide coupling using a fiber-taper. We have observed critical coupling to fundamental WG modes of a 600 μm diameter water droplet at 980 nm. The experimental challenges towards making, stabilizing and coupling to the droplet resonators are addressed in this paper.

  18. Note that the thickness of a liquid-liquid interface is usually characterized by an interfacial 90-10 width (the distance required for the surrounding liquid density to drop from 90% to 10% of its bulk value). Usually 90-10 width for a water-oil liquid is smaller than 1 nm and therefore the surface of a droplet in the cladding medium is extremely smooth. (see D. M. Mitrinovic et al., "X-ray reflectivity study of the water-hexane interface," J. Phys. Chem. B 13, 1779-1782, 1999) [CrossRef]
