May 17, 2019· Described in Optica, the chipscale clock is based on the vibrations, or “ticks,” of rubidium atoms confined in a tiny glass container, called a vapor cell, on a chip. Two frequency combs on chips act like gears to link the atoms’ highfrequency optical ticks to a lower, widely used microwave frequency that can be used in applications.
