Abstract :
We present a novel free-space communication link using orbital angular momentum (OAM) array encoding/decoding. By employing an array with 4 spatial locations each with 5 possible OAM beams, we experimentally demonstrate a high base OAM encoding/decoding with 625 states for free-space optical communications.
