Overview: Fiber cavities


  Fig. 1: Artist's impression of a fiber cavity.
 

Miniature cavities fabricated directly from optical fibers are a new tool for experiments in cavity Quantum Electrodynamics experiments. They are portable, robust and integrable devices for efficient light-atom interface. The interconversion of quantum information between light and matter using them makes fiber cavity a candidate for quantum memory in a quantum repeater node. Under "Research topics" find more information about our fiber mirror manufacturing and characterization setup and on our experiment on an atomic ensemble quantum memory which plans to use a fiber cavity.
