Understanding how line widths in microcombs will enable more precise measurements

Microcombs have widely differing application areas—they can help us discover planets outside our solar system as well as track diseases in our bodies. New research results at Chalmers University of Technology, Sweden, now give a deeper understanding of how the line width in the combs works, something that will, among other things, enable even more precise measurements in the future. And the discovery was made almost by coincidence.
