Experimental investigation of atom guiding in photonic bandgap fibers with Rb atoms

本项目将原子光学与纳米光子学相结合，以研制一种基于空心光子带隙光纤的新型波导为目标。利用空气引导光子带隙光纤，我们希望克服基于偶极子势的标准原子引导方案的局限性，实现并表征均匀、紧密和长距离的原子波导。在第一个资助期内，我们将集中于高通量加载方案以及引导特性的诊断。一个特别的目标将是研究和发展有效的冷却方案的引导原子，这在长期开放有趣的项目应用于集成原子干涉仪和可能的连续波相干物质波源。

This project targets the combination of the fields of atom optics and nanophotonics with the goal of a novel waveguide based on hollow photonic bandgap fibers. Using air guiding photonic bandgap fibers we want to overcome the limitations of standard dipole potential based atom guiding schemes and realize and characterize a homogeneous, tight and long distance atom guide. During the first funding period we will concentrate on high flux loading schemes as well as the diagnosis of guiding properties. A particular goal will be the investigation and development of efficient cooling schemes for the guided atoms, which in the long term open intriguing projects for applications in integrated atom interferometers and possibly a cw coherent matter wave source.
