Atom guiding in photonic bandgap fibres — •Stefan Vorrath, Mirja Michels, Sören Götze, Kai Bongs, and Klaus Sengstock — Universität Hamburg, Institut für Laser-Physik, Luruper Chaussee 149, 22761 Hamburg, Germany

In our project we investigate a new kind of atomic waveguide based on a 2D photonic band gap fibre providing nearly lossless guiding of light and atoms in the central hole of the fibre. The guiding mechanism is realized by capturing rubidium atoms from a MOT by means of a loading and a guiding red detuned dipole trap. To maximize the number of captured atoms from the MOT we have studied the loading process into the traps intensively. We will present the actual status of our project as well as future plans for experiments like atom cooling and atom interferometry.
