Microcombs are small photonic devices that could help improve the energy efficiency of the internet, monitor our health, or even discover new Earth-like exoplanets. Swedish researchers have developed a unique, game-changing microcomb that could bring these advanced applications a step closer.
What is a Microcomb?
A frequency comb is a unique laser source where the emission spectrum consists of a series of discrete, equally spaced frequency lines. It works similarly to a ruler made of light; markers set the frequency scale across the electromagnetic spectrum from ultraviolet to the mid-infrared, with each marker's location linked to a known reference.
