We demonstrate the fabrication of ultra-low-loss, all-fiber Fabry-Perot cavities that contain a nanofiber section, optimized for cavity quantum electrodynamics. By continuously monitoring the finesse and fiber radius during the fabrication of a nanofiber between two fiber Bragg gratings, we were able to precisely evaluate taper transmission as a function of radius. The resulting cavities have an internal round-trip loss of only 0.31% at a nanofiber waist radius of 207 nm, with a total finesse…

Fabrication of a centimeter-long cavity on a nanofiber for cavity quantum electrodynamics.

The fabrication of a 1.2 cm long cavity directly on a nanofiber using femtosecond laser ablation can enable the "strong-coupling" regime of cavity QED, with high cooperativity of 10-20, for a single atom trapped 200 nm away from the fiber surface.

Cavity-enhanced channeling of emission from an atom into a nanofiber

We study spontaneous emission of an atom near a nanofiber with two fiber-Bragg-grating (FBG) mirrors. We show that the coupling between the atom and the guided modes of the nanofiber can be

Fiber ring resonator with a nanofiber section for chiral cavity quantum electrodynamics and multimode strong coupling.

An optical fiber ring resonator that includes a tapered section with a subwavelength-diameter waist that is ideally suited for trapping ensembles of laser-cooled atoms along the nanofiber section is experimentally realized.

Cavity formation on an optical nanofiber using focused ion beam milling technique.

Optical interface created by laser-cooled atoms trapped in the evanescent field surrounding an optical nanofiber.

This technique opens the route towards the direct integration of laser-cooled atomic ensembles within fiber networks, an important prerequisite for large scale quantum communication schemes, and is ideally suited to the realization of hybrid quantum systems that combine atoms with, e.g., solid state quantum devices.

Demonstration of a state-insensitive, compensated nanofiber trap.

An optical trap is reported that localizes single Cs atoms ≃215  nm from the surface of a dielectric nanofiber by operating at magic wavelengths for pairs of counterpropagating red- and blue-detuned trapping beams, and differential scalar light shifts are eliminated and vector shifts are suppressed.

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.
