| 摘 要： | 现有太赫兹无线通信系统通常采用微波倍频或直接调源的方式。本文从太赫兹波空间调制技术出发,研究了一种基于直接调制技术的太赫兹无线通信系统。重点探索了一种基于石墨烯/半导体硅的复合结构(GOS),研究出调制速率达到1 MHz,调制深度50%以上,工作频带覆盖0.2 THz~2 THz频段的新型全光学太赫兹调制器。在此基础上,构建了330 GHz载波频率的太赫兹无线通信系统,实现了1 Mbps的通信速率。

| Abstract: | Currently, there are two methods to develop terahertz wireless communication system. One way is to use the microwave frequency doubling technology. Another approach is to direct modulate THz source. In this paper, different from both, we study a terahertz wireless communication system based on spatial direct modulation mode. We focus on exploring the structure of combining silicon and graphene(Graphene on Silicon, GOS), and have developed a new type of terahertz modulator with 1 MHz modulation rate, over 50% modulation depth and 0.2-2 THz frequency band. According to this study, we design and build a 330 GHz terahertz wireless communication system, and the system has achieved a communication rate of 1 Mbps. |
