The realization of miniaturized and integrated atom-optical elements at surfaces is of interest for many applications ranging from precision measurements to quantum information processing. Experimental work has been restricted so far to magnetic potentials above current-carrying wires. Our present work now addresses the case of optical potentials and some of its possibilities.
In our experiments, laser-cooled metastable argon atoms are optically confined in a quasi-2D geometry less than one micron from a gold-coated prism surface, realized by a single antinode of a far off resonance standing light wave. We will present results on the realization of novel integrated atom-optical elements in this planar waveguide layer, such as a continuous atom source (via evanescent-field optical optical pumping out of a magneto-optical surface trap (MOST)), a shutterable atom beam, a local atom detector and a quasi-1D lattice.
