DESCRIPTION:Prof. Jakob Reichel\,\nMember of Laboratoire Kastler Brossel o
 f the ENS\, Sorbonne Université\, Paris\, France\nAbstract\nOptical micro
 cavities are a very active research area due to their many applications ra
 nging from fundamental physics to telecommunications and quantum technolog
 ies. Motivated by our work on quantum metrology with ultracold atoms\, my 
 group has developed a fiber Fabry-Perot (FFP) cavity with laser-machined m
 irrors. 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 wi
 ll give an introduction to FFP cavities and their features\, and a brief r
 eview of some of their applications.\n\nBio\nJakob Reichel is distinguishe
 d professor of physics at Sorbonne Université and Laboratoire Kastler Bro
 ssel (LKB) of the ENS\, Paris. He studied physics in Bonn and Munich and e
 ntered the field of cold atoms in his PhD with C. Salomon and C. Cohen-Tan
 noudji 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 ColdQuanta.com and recipient of an ERC Advanced Grant on atomic
  quantum metrology. His group is known for their work in the field of quan
 tum technologies with ultracold atoms\, but also for their development of 
 novel tools for quantum physics.\n
