Low-Powered VCSELs Find a Wide Variety of Uses
By the end of 2018, nearly 1 million sq ft of new production space will have opened in the previous two years — space dedicated to making some of the world’s smallest and least power-hungry lasers. Known as vertical-cavity surface-emitting lasers, or VCSELs, these miniature devices have found use in 3D sensing, lidar, automated driving and manufacturing, high-speed data communication, laser printers, optical mice, and smartphones.
