Optical fibers with machined and coated endfacets can serve as high reflectivity mirrors to build low loss microcavities [1]. Featuring a small mode volume on the order of a few tens of cubic wavelengths, optical quality factors exceeding 106, and free space accessability to the cavity modes, they are well suited to study nanoscale systems with high sensitivity. We will present first steps towards coupling a nitrogen-vacancy centers in nanodiamonds to the fiber cavity. First experimental results on absorption spectroscopy with gold nanoparticles will be discussed.
