Atomic spectroscopy and quantum interference in on-chip hollow-core waveguides

Holger Schmidt

Miniaturized atomic vapor cells can be built on a semiconductor chip using hollow-core waveguide technology. We review the status of these integrated spectroscopy chips, including the observation of signatures of quantum interference on a chip.

Optical Spectroscopy of Ultracold Atoms on an Atom Chip

Andreas Günther, H. Bender, Alexander Stibor +2 more

We experimentally demonstrate optical spectroscopy of magnetically trapped atoms on an atom chip. High resolution optical spectra of individual trapped clouds are recorded within a few hundred milliseconds. Detection sensitivities close to the single atom level are obtained by photoionization of the excited atoms and subsequent ion detection with a channel electron multiplier. Temperature and decay rates of the trapped atomic cloud can be monitored in real time for several seconds with only little detection losses. The spectrometer can be used for investigations of ultracold atomic mixtures and for the development of interferometric quantum sensors on atom chips.We experimentally demonstrate optical spectroscopy of magnetically trapped atoms on an atom chip.

Quantum interference effects in rubidium vapor on a chip

Bin Wu, John F. Hulbert, Aaron R. Hawkins +1 more

Harnessing the unique optical quantum interference effects associated with electromagnetically induced transparency (EIT) on a chip promises new opportunities for linear and nonlinear optical devices. Here, we review the status of integrated atomic spectroscopy chips that could replace conventional rubidium spectroscopy cells. Both linear and nonlinear absorption spectroscopy with excellent performance are demonstrated on a chip using a self-contained Rb reservoir and exhibiting a footprint of only 1.5cm x 1cm. In addition, quantum interference effects including V-scheme and Λ-scheme EIT are observed in miniaturized rubidium glass cells whose fabrication is compatible with on-chip integration.Harnessing the unique optical quantum interference effects associated with electromagnetically induced transparency (EIT) on a chip promises new opportunities for linear and nonlinear optical devices.
