Phys. Rev. Lett. 89, 220402 (2002) [4 pages]Interferometer-Type Structures for Guided AtomsReceived 12 July 2002; published 7 November 2002 We experimentally demonstrate interferometer-type guiding structures for neutral atoms based on dipole potentials created by microfabricated optical systems. As a central element we use an array of atom waveguides being formed by focusing a red-detuned laser beam with an array of cylindrical microlenses. Combining two of these arrays, we realize X-shaped beam splitters and more complex systems like the geometries for Mach-Zehnder and Michelson-type interferometers for atoms. © 2002 The American Physical Society URL:
