Atomic Fiber Optic Switch
Researchers have succeeded in creating a microphotonic optical switch, in which a single atom redirects photons down different fiber paths. Fiber-optical switch controlled by a single atom Danny O'Shea, Christian Junge, Jurgen Volz, and Arno Rauschenbeutel Vienna Center for Quantum Science and Technology, Atominstitut, Vienna University of Technology, 1020 Vienna, Austria (Dated: November 17, 2018) We demonstrate highly ecient. Making these switches small enough to manipulate light would enable quantum communication and information technology. A switch activated by a single control photon for routing a single target photon from either of two switch inputs to either of two switch outputs.
