摘　　要：太赫兹(Terahertz,THz)波的定义为频率从0.1~10 THz范围的电磁波。THz通信技术被认为是用于6G应用场景的新兴技术,该技术的优点在于具有更宽的信道带宽,并可以提供高达数T比特每秒(Tbit/s)的超高速数据传输。介绍了面向6G无线通信系统应用颇具潜力的几种THz光子学收发器的工作原理和研究进展,包括单行载流子光电二极管(UTC-PD)、肖特基二极管(SBD)、THz量子级联激光器(THz QCL)和THz量子阱探测器(THz QWP)。研究表明,这4种收发器在未来6G无线通信中具有潜在的应用价值。Terahertz(THz)electromagnetic waves are defined as waves with frequencies ranging from 100 GHz to 10 THz.THz communication technology,which is considered as an emerging technology for sixth generation(6G)mobile communication application scenarios,features broader bandwidth and can provide ultra-high speed data rate up to T bits per second(Tbps).This paper reviews the working principle and research progresses of several potential photonic terahertz transceivers for 6G wireless communication systems,including uni-traveling carrier photodiode(UTC-PD),Schottky diode(SBD),terahertz quantum cascade laser(THz QCL)and terahertz quantum well photodetector(THz QWP).It has been realized that these four transceivers have potential application value in future 6G wireless communications.
