Paper Abstract

We report the recent progress of the experiments on guiding atoms by evanescent waves in micron-sized hollow optical fibers. The lateral manipulation accuracy is enhanced up to 1 micron with a large increase of more than 50 times on the guided atom flux. Moreover, the frequency tuning enables the fine control of the guided flux with a numerical accuracy of 10 atom/s. The atom-guidance scheme is applied to in-line isotope separation on rubidium atoms and measurement of the cavity quantum electrodynamic effect in a cylindrical dielectric. In addition, the feasibility of fabricating micron-sized structures with nanometric depth is discussed including the manipulation of a small number of laser-cooled atoms.
