激光-太赫兹融合通信:关键技术与未来展望OA
Laser-terahertz hybrid communication:key technologies and future prospects
激光通信与太赫兹通信因其大带宽与高速率特性,被视为满足6G时代超高速、低延迟通信需求的两项关键技术.激光通信因其在大气层中的低损耗传播特性而在星地通信中应用前景广阔,但在云雾天气时衰减严重;太赫兹通信对云雾的高穿透性可以弥补这点不足,但在非云雾天气下传输速率不及激光通信.为提升星地通信系统的可靠性与适应性,重点关注激光与太赫兹融合通信方案,总结激光与太赫兹融合通信的研究现状,包括光子辅助太赫兹生成、光载太赫兹通信等关键技术,并提出共源与非共源两种激光-太赫兹融合通信架构.通过分析当前挑战,展望了激光-太赫兹融合通信的未来发展方向,为构建可靠、灵活的激光-太赫兹融合系统提供理论支持.
Laser communication and terahertz communication are key technologies for 6G,thanks to their large bandwidth and high-speed performance,essential for meeting the era's demands for ultra-high speed and low latency.However,laser communication suffers from low transmission efficiency due to at-mospheric attenuation in cloudy or foggy conditions.Terahertz communication,offering high penetration through clouds and fog,has a relatively low transmission rate.To improve the reliability and adaptability of communication systems,this paper focuses on hybrid laser-terahertz communication.It reviews current research,covering key technologies such as laser-assisted terahertz signal generation and laser-terahertz communication architecture.By analyzing existing challenges,this paper outlines future directions of laser-terahertz hybrid communication,providing theoretical support for its further development.
