Demonstration of a continuously guided atomic interferometer by single-zone optical excitation

We demonstrate an atomic interferometer in which the atom passes through a single-zone optical beam consisting of a pair of bichromatic counterpropagating fields. During the passage, the atomic wave packets in two distinct internal states trace out split trajectories, guided by the optical beams, with the amplitude and spread of each wave packet varying continuously, producing fringes that can reach a visibility close to unity. Theoretically, the rotation sensitivity of this continuous interferometer (CI) can be comparable to that of the Borde-Chu interferometer. The relative simplicity of the CI makes it a potentially better candidate for practical applications.

We present work on versatile, compact optical components for waveguided atom interferometry with rotation sensing in mind. These diffractive optical elements: static Fresnel zone plates (FZPs), paired with a dynamic spatial light modulator, expand on the previous design and construction in our group of FZPs for smooth, red-detuned optical waveguides, allowing a wider range of functionality such as dark trapping with blue-detuned light and the generation of multiple, distinct waveguides from single FZPs. Our experiment utilises Bose-Einstein condensates of Rb-87 for interferometry, currently in a free-space configuration, by introducing such waveguides we can reduce the scale of this apparatus while increasing sensitivity to rotation.
