Integrated atom optics: atom chips

Atom optics is a maturing field of research. As a result of rapid progress in laser cooling and microfabrication technology, atom optics has seen great development with regard to miniaturization and integration. We review the lastest experimental advances in atom chip fabrication, a main focus of integrated atom optics, including various types of atom guides, improvement of the atom chips, application of the clips in Bose－Einstein condensate future potential applications.
