Multiple lasers could be replaced by a single microcomb
Every time we send an e-mail, a tweet, or stream a video, we rely on laser light to transfer digital information over a complex network of optical fibers. Dozens of high-performance lasers are needed to fill up the bandwidth and to squeeze in an increasing amount of digital data. Researchers have now shown that all these lasers can be replaced by a single device called a microcomb.
