Fiber Fabry-Perot cavities (FFPC), formed by micro-machined mirrors on the end-facets of optical fibers [1], are used in an increasing number of technical and scientific applications. Here, we present the fabrication process of the micro mirrors and two different approaches to construct FFPC: a piezo-mechanically actuated cavity with feedback based on the Pound-Drever-Hall locking technique and a novel rigid cavity design that makes use of the high passive stability of a monolithic cavity spacer and employs thermal self-locking and external temperature tuning [2]. Furthermore, we discuss effects specific to FFPC such as Raman scattering and asymmetric line shapes. Finally, we present our latest results regarding imaging and strong coupling of small ensembles of 87Rb neutral atoms to one of our fiber cavities.
