But first, a little background. Most laser-based communications -- think fiber optics, commonly used for things like high-speed internet -- is transmitted in the form of a laser (optical) beam traveling through a cable. Optical communications is exceptionally fast but is limited by the fact that it must travel through physical cables. Bringing the high-capacity capabilities of lasers to untethered and roving applications -- such as to airplanes, drones, submarines, and satellites -- is truly exciting and potentially game-changing.
