Optical microcavities are a very active research area due to their many applications ranging from fundamental physics to telecommunications and quantum technologies. Motivated by our work on quantum metrology with ultracold atoms, my group has developed a fiber Fabry-Perot (FFP) cavity with laser-machined mirrors. Due to its original combination of features, this cavity has far surpassed our original expectation and is now being used in a large number of research laboratories around the globe, and first commercial versions are becoming available. FFPs are used for fundamental research on quantum entanglement, but also for applications as diverse as solid-state single-photon sources, scanning probe microscopy, and trace gas analysis. I will give an introduction to FFP cavities and their features, and a brief review of some of their applications.

Jakob Reichel is distinguished professor of physics at Sorbonne Université and Laboratoire Kastler Brossel (LKB) of the ENS, Paris. He studied physics in Bonn and Munich and entered the field of cold atoms in his PhD with C. Salomon and C. Cohen-Tannoudji in Paris. Before joining LKB, he worked with T. W. Hänsch at the Max Planck Institute for Quantum Optics, where he demonstrated the first microchip trap for ultracold atoms, now known as the atom chip. He is co-founder of and recipient of an ERC Advanced Grant on atomic quantum metrology. His group is known for their work in the field of quantum technologies with ultracold atoms, but also for their development of novel tools for quantum physics.
