| Research Abstract |
Around an optical nanofiber(ultra-thin optical fiber with sub-micron diameter), mode density of electromagnetic fields is strongly confined to the guided modes of nanofiber. We have experimentally demonstrated that, due to the strong confinement, fluorescence photons from atoms on nanofiber are efficiently channeled into the guided modes with an efficiency higher than 20%. Moreover, we have shown theoretically that this efficiency can be enhanced to 90% or higher by incorporating a cavity structure on nanofiber. Method to fabricate nanofiber cavity has also been developed. The results may open a new route for quantum optics and quantum information technologies.
