Télécom Paris, TU Darmstadt and UCLA demonstrate FSO networking with two uni-directionally coupled QCLs.
Chaos theory: experimental setup for free-space comms based on QCLs.Free-space optical communication, the communication between two devices at a distance using light to carry information, is a highly promising system for achieving high-speed communication. This system of communication is known to be immune to electromagnetic interference. While some studies have highlighted the possible advantages of free-space optical communication, this system of communication has so far come with certain limitations. Most notably, it is known to offer limited security against eavesdroppers.
