Abstract
We report the fabrication of a 1.2 cm long cavity directly on a nanofiber using femtosecond laser ablation. The cavity modes with finesse values in the range of 200–400 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 [Phys. Rev. A 80, 053826 (2009) [CrossRef] ]. Such cavity modes can still maintain the transmission between 40%–60%, suggesting a one-pass intracavity transmission of 99.53%. Other cavity modes, which can enable cooperativity in the range of 3–10, show transmission over 60%–85% and are suitable for fiber-based single-photon sources and quantum nonlinear optics in the “Purcell” regime.
