Powerful and precise multi-color lasers now fit on a single chip
A few years ago, researchers in Michal Lipson’s lab noticed something remarkable. They were working on a project to improve LiDAR, a technology that uses lightwaves to measure distance. The lab was designing high-power chips that could produce brighter beams of light. “As we sent more and more power through the chip, we noticed that it was creating what we call a frequency comb,” says Andres Gil-Molina, a former postdoctoral researcher in Lipson’s lab. A frequency comb is a special type of light that contains many colors lined up next to each other in an orderly pattern, kind of like ...
