Coding and decoding data by multiplexing vortex beams in free space

A novel concept of coding/decoding data is proposed by multiplexing vortex beams for short-haul-free-space light communication. Eight vortex beams carrying different orbital angular momentum (OAM) modes (-5, 3, -2, 1, 5, -3, 2, -1) are employed to code the initial information sequences into each 256...
