But that's not just true for people (or Muppets), it's also true for lasers.

According to new research from the USC Viterbi School of Engineering, recently published in Nature Photonics, adding two lasers together as a sort of optical "it couple" promises to make wireless communications faster and more secure than ever before. 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.
