Femtosecond-precise soliton microcomb chips suppress timing jitters for space navigation, lidar, and ultrafast communications

"no need for large, lab-based lasers... stops jitter (caused by environmental noise/ intracavity power fluctuations) which distorts ultrashort light pulse timing within microresonators, using dispersion-managed silicon nitride microresonators operating at an 89 GHz repetition rate... reduces avoided mode crossings... single-soliton state consistently produced cleanest signal... negligible center frequency shifts, which helps to prevent noise conversion processes related to center frequency shifts... quantum measurement systems"
