This schematic illustration shows the diffractive element in the high-power microcomb source separating comb lines spectrally. Credit: Courtesy of Michal Lipson lab While developing LiDAR technology, scientists unexpectedly discovered how to generate multiple laser colors from a single chip. Their innovation could transform data centers and communications by delivering faster, cleaner, and more efficient light sources. Accidental Discovery in the Lab A few years ago, researchers in Michal Lipson’s lab came across something unexpected. Their work at the time focused on improving LiDAR, a technology that measures distance using lightwaves. The team was designing powerful chips capable of generating brighter,...
