Visualization 1: Demonstration of All-light Communication Network

As shown in Visualization 1, the all-light communication network (ALCN) consists of the blue light communication, white light communication, deep ultraviolet light communication, and laser diode-based communication, spanning space, air, land, and sea. Full-duplex real-time video communication in the ALCN and addressable transmission via wireless and wired access to the ALCN is demonstrated, in this way, the ALCN provides a promising scheme for future space–air–sea interconnections.
