Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of a comb. 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. /news/2025-05-chip-scale-soliton-microcombs-femtosecond.html Optics & Photonics Wed, 21 May 2025 15:40:30 EDT news667060828 What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors?
