Quantum metrology with Fiber Fabry-Perot cavities (Conference Presentation)
Author(s): Jakob Reichel

Paper Abstract

The development of laser-machined, ultralow roughness micromirrors on optical fiber tips has enabled a new type of high-finesse Fiber Fabry-Perot cavities (FFPs). These microcavities are used very successfully in an increasing number of quantum technology applications, reaching from single-photon sources with various solid-state emitters to entanglement generation in ultracold atomic ensembles. They are also attractive for general photonics applications where high cavity finesse is desired, combinin narrow resonance width and large stopband with high transmission, excellent passive stability and built-in fiber coupling. I will give a short overview of this cavity technology and describe an experiment where we are using a next-generation FFP cavity to generate long-lived spin squeezed states in an atomic clock on a chip.
