Integration of Light and Atom Optics onto an Atom Chip — •Albrecht Haase, Ron Folman, and Jörg Schmiedmayer — Physikalisches Institut, Universität Heidelberg, Philosophenweg 12, 69120 Heidelberg

A large variety of guiding and trapping potentials can be designed by bringing cold neutral atoms close to charged and current carrying objects forming traps, guides and beamsplitters. These versatile atom optical elements can be easily miniaturized and integrated onto an Atom Chip as it was recently demonstrated in our lab [1]. Atom Chips may be used for fundamental research issues such as decoherence and entanglement or for applications like clocks, sensors and quantum information processing.

To be able to realize the full potential of these devices, one would like to develop on-chip, miniaturized, high efficiency, high resolution, single atom detectors with the ability to detect both external and internal degrees of freedom. Here we present first steps into this direction. We discuss the feasibility of bringing light onto the Atom Chip using wave guides and give an example of integrated Fabry-Perot micro cavity resonators. We discuss a scheme how to detect the atoms by their coupling to the resonator’s light field.
