'Comb on a Chip' Powers New Atomic Clock Design

07-22-14

Scott Diddams who was a 2012 Caltech Moore Distinguished Scholar and is a Project Lead at National Institute of Standards and Technology (NIST) and colleagues including Professor Kerry Vahala have demonstrated a new design for an atomic clock that is based on a chip-scale frequency comb, or a microcomb. The microcomb clock is the first demonstration of all-optical control of the microcomb, and its accurate conversion of optical frequencies to lower microwave frequencies. Caltech researchers made the 2-millimeter-wide silica disk that generates the frequency comb for the new clock. [NIST Press Release] [Learn More]
