They serve as precise rulers for measuring time and frequency, and have become essential tools in applications such as lidar, high-speed optical communications, and space navigation. Traditional frequency combs rely on large, lab-based lasers. However, recent advancements have led to the development of chip-scale soliton microcombs, which generate ultrashort pulses of light within microresonators.<\/p>\n<p>One of the key challenges for soliton microcombs is <a href=\"https:\/\/phys.org\/tags\/timing\/\" rel=\"tag\" class=\"\">timing<\/a> jitter, which refers to tiny fluctuations in the timing of their light pulses. These fluctuations, caused by <a href=\"https:\/\/phys.org\/tags\/environmental+noise\/\" rel=\"tag\" class=\"\">environmental noise<\/a> or internal instabilities, can degrade the precision and reliability of systems that rely on exact timing. For example, in lidar, jitter can cause uncertainty in distance measurements, and in high-speed data transmission, it can introduce signal distortion and reduce data integrity.<\/p>\n<p>As <a href=\"https:\/\/www.spiedigitallibrary.org\/journals\/advanced-photonics-nexus\/volume-4\/issue-03\/036011\/Mapping-ultrafast-timing-jitter-in-dispersion-managed-89GHz-frequency-microcombs\/10.1117\/1.APN.4.3.036011.full\" target=\"_blank\">reported<\/a> in <i>Advanced Photonics Nexus<\/i>, an international research team has addressed this problem by developing a new platform based on dispersion-managed (DM) silicon nitride (Si<sub>3<\/sub>N<sub>4<\/sub>) microresonators operating at an 89 GHz repetition rate.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of a comb.
