Abstract

Interfacing cold atoms with nanophotonic waveguides and resonators promises stronger atom-light interactions and leads to new paradigms for quantum optics. Here, we demonstrate coupling single atoms to a nanophotonic whispering-gallery-mode resonator using two different methods. The first one is an optical guiding technique that makes use of diffracted light from a nanophotonic waveguide to direct cold atoms to the evanescent region of the resonator. The second one is an optical conveyor-belt consisting of a moving optical lattice for controlled delivery of trapped atoms. Our demonstration enables new applications with scalable light-matter interface based on cold atoms coupled to nanophotonic circuits.
