We report loading of laser-cooled caesium atoms into a hollow-core photonic-bandgap fiber and confining the atoms in the fiber’s 7μm diameter core with a red-detuned dipole trap. In this system, the atom-photon interaction probability is in the range of 0.5% and optical depths exceeding 100 can be achieved. We discuss the outlooks for photon storage and nonlinear optics at low light levels, such as cross-phase modulation and single-photon wavelength conversion, in this system.
