摘要
随着无线数据传输速率需求的爆炸式增长,太赫兹频段(0.1~10 THz)以其丰富的频谱资源备受关注。太赫兹光子学的通信技术因具有超宽带、调制效率高、谐波干扰小等技术优势,被公认可以极大地促进数据传输速率向Tbit/s发展。本文以光子太赫兹通信3个方面关键技术的综述分析为基础,包括光子太赫兹通信的收发器件、基带信号处理技术、系统架构与实验验证等,探讨光子太赫兹通信技术的发展趋势,并从宏观与微观尺度展望光子太赫兹通信的潜在应用场景。
With the explosive growth of wireless data rate,the terahertz band(0.1~10 THz)has attracted increasing attention due to its rich frequency resources.The terahertz photonic communication technology has advantages such as broadband,high modulation efficiency and low harmonic distortions.It is expected to greatly promote the wireless transmission data rate toward the Tbit/s level.Based on the review of the key technologies for realizing ultra-high-rate terahertz photonic communication,including terahertz communication transceivers,digital baseband signal processing technologies,terahertz photonic communication system architectures and experimental demonstrations,the future development trends of the terahertz photonic communication technologies are discussed.The application scenarios of terahertz photonic technology from the micro to macro scales are also analyzed.
