Optical wireless communication (OWC) stands out as one of the most promising technologies in the sixth-generation (6G) mobile networks. The establishment of high-quality optical links between transmitters and receivers plays a crucial role in OWC performances. Here, by a compact beam splitter composed of a metasurface and a fiber array, we proposed a wide-angle (~120°) OWC optical link scheme that can parallelly support up to 144 communication users. Utilizing high-speed optical module sources and wavelength division multiplexing technique, we demonstrated each user can achieve a communication speed of 200 Gbps which enables the entire system to support ultra-high communication capacity exceeding 28 Tbps. Furthermore, utilizing the metasurface polarization multiplexing, we implemented a full range wide-angle OWC without blind area nor crosstalk among users. Our OWC scheme simultaneously possesses the advantages of high-speed, wide communication area and multi-user parallel communications, paving the way for revolutionary high-performance OWC in the future.
光无线通信（OWC）是第六代（6G）移动网络中最具前景的技术之一。在发射器和接收器之间建立高质量的光链路对OWC性能起着至关重要的作用。在此，我们通过由超表面和光纤阵列组成的紧凑型分束器，提出了一种广角（约120°）OWC光链路方案，该方案可并行支持多达144个通信用户。利用高速光模块源和波分复用技术，我们证明每个用户都能实现200 Gbps的通信速度，这使得整个系统能够支持超过28 Tbps的超高通信容量。此外，利用超表面偏振复用，我们实现了全范围广角OWC，用户之间无盲区且无串扰。我们的OWC方案同时具备高速、宽通信区域和多用户并行通信的优势，为未来高性能OWC的变革铺平了道路。
