Integrated terahertz (THz) technology is of great significance for driving high-speed communication, sensing, and imaging with its advantages of miniaturization, low cost, and high efficiency. Recent research has focused on highly-efficient transmitters and ultrafast detectors, as well as exploring new devices for coupling, transmission, and polarization control. However, multidimensional on-chip multiplexing and demultiplexing techniques in the THz region still remains unexplored, due to the lack of multifunctional integrated components and systems. Here, a novel silicon-based integrated multidimensional THz (de)multiplexer for high-capacity communication is proposed and demonstrated based on ring resonators and polarization beam splitter-rotators, which simultaneously enable the manipulation of THz polarization and frequency. Furthermore, a THz communication system operating in the 380 GHz band is experimentally demonstrated. By using on-chip polarization- and frequency-division multiplexing techniques, an aggregate data rate of 8 Gbit s−1 is successfully achieved with quadrature phase-shift keying modulation scheme. This work provides a spectrally efficient way for accelerating the development of on-chip THz technologies and the application in future large-volume communications.

用于多维太赫兹通信的片上极化和频分解复用
集成太赫兹（THz）技术以其小型化、低成本、高效率的优势，对于驱动高速通信、传感和成像具有重要意义。最近的研究集中在高效发射器和超快探测器，以及探索用于耦合、传输和偏振控制的新设备。然而，由于缺乏多功能集成组件和系统，太赫兹区域的多维片上复用和解复用技术仍未得到探索。在这里，基于环形谐振器和偏振分束器旋转器，提出并演示了一种用于大容量通信的新型硅基集成多维太赫兹（解）复用器，它同时能够操纵太赫兹偏振和频率。此外，实验演示了工作在 380 GHz 频段的太赫兹通信系统。通过使用片上极化和频分复用技术，总数据速率为 8 Gbit s-1通过正交相移键控调制方案成功实现。这项工作为加速片上太赫兹技术的发展和在未来大容量通信中的应用提供了一种高效的频谱方式。
