Atom Optics with Microfabricated Optical Elements — •Felix B.J. Buchkremer, Rainer Dumke, Tobias Müther, Michael Volk, Gerhard Birkl, and Wolfgang Ertmer — Institut für Quantenoptik, Universität Hannover, Welfengarten 1, 30167 Hannover, Germany

We introduce a new direction in the field of atom optics, atom interferometry, and neutral-atom quantum information processing. It is based on the use of microfabricated optical elements for the manipulation of atoms with light fields [1]. Together with systems based on miniaturized and microfabricated electrostatic and magnetic devices, this novel approach will launch a new field which we call ATOMICS for ATom Optics with MICro-Structures. This approach has a large potential for combining the advanced possibilities of atom optical measurement systems and the state-of-the-art manufacturing techniques of micro- and nanofabrication.

We present several configurations where microfabricated optical elements can be used to create versatile and integrated atom optical devices in a compact fashion such as multiple trapping potentials, atomic wave guides, beam splitters, atom interferometers, and miniaturized atom sources and report on the progress of the experimental implementation. Supported by the SFB 407 of the DFG.
