Miniaturizing optical resonators - Fiber-based Fabry-Perot cavities — •Usman Adil1, Franziska Haslinger2, Michael Förg2, Sambit Mitra2, Manuel Nutz2, Jonathan Noé2, and Thomas Hümmer2 — 1LMU Munich — 2Qlibri GmBH
Microscopic optical resonators have proven to be a versatile tool through their ability to enhance light-matter interaction. Constructing the mirrors on the end-facets of optical fibers offers a compact and tunable solution with intrinsic fiber coupling: Fiber Fabry-Perot Cavities (FFPCs). Successful experimental examples/applications range from non-destructive qubit readout in quantum information processing over sensing applications of gases or liquids to the usage as frequency filter for optical signals. Here, we present the prototype of a readily available FFPC and provide first insights on fiber alignment and positioning. Core parameters like finesse, length stability and mode matching are analyzed as a function of fiber type, mirror shape and coating properties.
