We experimentally demonstrate visible-light co ding/de co ding utilizing hexadecimal vector beam array for parallel communication link. The hexadecimal base mode is investigated and 128-ary is also available. We present vector beam array carrying 4×6/6×8/12×16 hexadecimal numbers and error-free data stream transmission performance is also demonstrated.
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.
