Dual‐Metasurface‐Integrated Fiber Array for Bidirectional Cylindrical‐Vector‐Beam Multiplexed Communication Using Off‐Axis Spatial Manipulation

ABSTRACT Free‐space optical (FSO) communication is expected to support 6G networks, and cylindrical vector beam (CVB) multiplexing offers a promising space‐division multiplexing (SDM) dimension for high‐capacity FSO links. However, conventional CVB generators offer limited bidire...
