太赫兹（THz）波在宽带无线通信中的应用越来越受到人们的关注。特别是，使用275 GHz以上的频率是无线电科学家和工程师强烈关注的问题之一，因为这些频带尚未分配给特定的活动服务，并且有可能使用超大带宽进行超宽带无线通信。用于信号生成、调制和检测的光子技术的引入不仅对提高带宽和/或数据速率有效，而且对联合收割机光纤（有线）和无线网络的组合也有效。本文综述了太赫兹无线通信的最新进展，利用电信为基础的光子技术，向100 Gbit/s。(C)2013年美国光学学会
There has been an increasing interest in the application of terahertz (THz) waves to broadband wireless communications. In particular, use of frequencies above 275 GHz is one of the strong concerns among radio scientists and engineers, because these frequency bands have not yet been allocated at specific active services, and there is a possibility to employ extremely large bandwidths for ultra-broadband wireless communications. Introduction of photonics technologies for signal generation, modulation and detection is effective not only to enhance the bandwidth and/or the data rate, but also to combine fiber-optic (wired) and wireless networks. This paper reviews recent progress in THz wireless communications using telecom-based photonics technologies towards 100 Gbit/s. (C) 2013 Optical Society of America
