Using self-resonant coils in a strongly coupled regime, we experimentally demonstrated efficient nonradiative power transfer over distances up to 8 times the radius of the coils. We were able to transfer 60 watts with ∼40% efficiency over distances in excess of 2 meters. We present a quantitative model describing the power transfer, which matches the experimental results to within 5%. We discuss the practical applicability of this system and suggest directions for further study.

Observation of strong coupling between one atom and a monolithic microresonator

Strong coupling is achieved, with the rate of coherent coupling exceeding the dissipative rates of the atom and the cavity, and this work opens the way for investigations of optical processes with single atoms and photons in lithographically fabricated microresonators.
