摘　　要：光子辅助技术路线有助于实现高频无线通信与光纤有线传输的无缝融合,是6G网络实现大容量无线通信潜在的关键使能技术之一。针对光偏振复用信号的桥接传输,提出了基于单输入单输出无线链路的透明传输方案,可有效解决传统2×2多输入多输出无线链路中长距离传输多天线对准困难、双通道间串扰大和信道不均衡等难题。采用提出的方案基于单通道分别实现了离线超400 Gbps和实时125 Gbps超100米距离的大容量光子辅助亚太赫兹无线通信系统演示。Photonics-assisted technology plays a vital role in achieving the seamless integration of high-frequency wireless communication and fiber-optic wired transmission.It is considered as one of the potential key enabling technologies for large-capacity wireless communication in 6G networks.In this study,we propose a transparent transmission scheme based on a single-input single-output wireless link to effectively solves the challenges faced in traditional 2x2 multiple-input multiple-output wireless links,such as difficulties in antenna alignment over long distances,large inter-channel interference,and channel imbalance.By adopting this scheme,we successfully demonstrate high-capacity photonics-assisted sub-terahertz wireless communication systems,achieving a data rate exceeding 400 Gbps offline and real-time transmission of 125 Gbps over a distance of more than 100 meters.
