摘要

我们通过实验演示了 300 GHz 三角积分调制（DSM）信号在中空芯光纤（HCF）和 2 m 无线链路上的传输。通过使用双载波调制，我们有效地提高了太赫兹信号的信噪比。同时，我们还成功解决了在光纤链路中传输太赫兹（THz）光信号时因色度色散（CD）引起的波长偏离问题，并成功演示了在 2 千米长的空芯光纤和 2 米长的无线链路上传输 24 Gbaud OOK-DSM 信号。演示系统支持 1024 QAM 的移动前传 (MFH)。同时，HCF 因其低传输延迟特性，更适用于对延迟敏感的前端链路。因此，该演示系统为光纤难以部署地区的 MFH 提供了一种前景广阔的方案。

Dual Carrier Modulation 300 GHz DSM Terahertz Wave Signals Transmitted via Hollow-Core Fiber

We experimentally demonstrated the transmission of 300 GHz Delta-sigma Modulation (DSM) signals over Hollow-core fibers (HCF) and 2 m wireless links. By using dual-carrier modulation, we effectively improve the signal-to-noise ratio of the generated terahertz signal. At the same time, through HCF, we have successfully solved the problem of wavelength walk-off of optical terahertz (THz) signals caused by chromatic dispersion (CD) when transmitted in fiber links, and successfully demonstrated the transmission of a 24 Gbaud OOK-DSM signal over 2 km of HCF and 2 m of wireless links. The demonstration system supports mobile fronthaul (MFH) of 1024 QAM. At the same time, HCF is more suitable for delay-sensitive fronthaul links due to its low transmission delay characteristics. Therefore, the demonstrated system provides a promising scheme for MFH in areas where fiber is difficult to deploy.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
