Design of a trapping potential for detecting single atoms by a microdisk resonator on a chip
Design of a trapping potential for detecting single atoms by a microdisk resonator on a chip
We investigate simultaneous optical trapping and optical detection of a single Rb atom near the surface of a toroidal microdisk. Light is coupled into two high-Q whispering-gallery modes of the disk which provide attractive and repulsive potentials, respectively, via their evanescent fields. The sum potential including van-der-Waals and Casimir-Polder surface forces exhibits a minimum at distances of the order of 100 nm from the disk surface.
The back-action of an atom held in this trap on the light fields is sufficiently strong to provide a measurable effect. We discuss atom trapping and detection properties in dependence on a variety of system parameters.

Abstract
We investigate simultaneous optical trapping and optical detection of a single Rb atom near the surface of a toroidal microdisk. Light is coupled into two high-Q whispering-gallery modes of the disk which provide attractive and repulsive potentials, respectively, via their evanescent fields. The sum potential including van-der-Waals and Casimir-Polder surface forces exhibits a minimum at distances of the order of 100 nm from the disk surface.
The back-action of an atom held in this trap on the light fields is sufficiently strong to provide a measurable effect. We discuss atom trapping and detection properties in dependence on a variety of system parameters.
