Abstract
A guided coherent atom source () includes elements for generating neutral atoms in a gaseous state (), elements for cooling the atoms gas (), elements for generating a magnetic field (), including an electro-magnetic micro-chip () deposited on a surface () of a substrate (), and capable of condensing the atoms in a magnetic trap, elements for generating an electro-magnetic RF field capable of extracting the condensed atoms, optical elements () for emitting and directing an optical coherent beam () toward the condensed atoms able to guide the condensed atoms, characterized in that the optical elements () and the electro-magnetic micro-chip () are integrated onto the same substrate (). An atomic interferometer using such a source is also disclosed.
