Nano zipper cavity, responsive to single photons, promises sensitive force detection, light-tunable communication circuits

A new nanoscale photonics device exploits the mechanical properties of light to create an optomechanical cavity in which interactions between light and motion are greatly strengthened and enhanced. These interactions are the largest demonstrated to date, notes Oskar Painter, associate professor of applied physics at the California Institute of Technology (Caltech; Pasadena, CA) and the principal investigator on the research.
