Query: Coherent coupling of single molecules to on-chip ring resonators   We report on cryogenic coupling of organic molecules to ring microresonators
obtained by looping sub-wavelength waveguides (nanoguides). We discuss
fabrication and characterization of the chip-based nanophotonic elements which
yield resonator finesse in the order of 20 when covered by molecular crystals.
Our observed extinction dips from single molecules reach 22%, consistent with
the expected Purcell enhancements up to 11 folds. Future efforts will aim at
efficient coupling of a handful of molecules via their interaction with a ring
microresonator mode, setting the ground for the realization of quantum optical
cooperative effects.
