Atom guiding in a photonic band gap fibre — •Stefan Vorrath, Sönke Möller, Kai Bongs, and Klaus Sengstock — Universität Hamburg, Institut für Laser-Physik, Hamburg, Germany

In our project we investigate a promising new kind of atomic waveguide based on a 2D photonic band gap fibre which provides nearly lossless guiding of light and atoms in the central hole over long distances. Our guiding mechanism is realized by capturing, compressing and cooling rubidium atoms from a dark spot MOT into the guiding trap composed of several watts of laser power at 1064nm. After optimizing the loading process of our trap we capture about 3 million atoms in front of the fibre. Our newest results will be presented.
