Polarization-Selective Multiplexing Metasurface Using OAM Interleaving

We propose a passive complex-amplitude meta-surface for high-capacity vectorial holography, which enables secure and scalable optical communication by independently modulating$E_{x}$and$E_{y}$through interleaved orbital angular momentum (OAM) modes and polarization states. Utilizing a geometry-based lookup table, the metasurface encodes distinct holograms for each polarization. Preliminary results demonstrate an improved bit error rate with higher signal-to-noise ratio, confirming the robustness of this approach. This work represents a novel integration of OAM and polarization multiplexing through passive complex-amplitude modulation, offering a high-capacity and noise-tolerant solution for scalable optical communication systems.
