Accurately measuring frequencies of light is required for timekeeping and many science experiments and technologies. Frequency combs, invented in 2000, are used to complete these measurements. However, most of them are large and cumbersome. In 2009, researchers developed a way to make much smaller combs, but they came with their own challenges. New research finds that a novel way of generating frequency combs could address these challenges, leading to compact frequency combs with untold applications.
