Hybrid, reconfigurable Fresnel zone plate waveguides for ultracold atoms

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.
