Sub-THz and THz Signal Generation Using Photonic and Electronic Techniques (Invited Paper)

To enable the use of the sub-THz and THz region of the electromagnetic spectrum from 100GHz to 10THz for next generation high-speed wireless communication and other emerging applications, it is important to generate the signal in this frequency range with high output power and high efficiency in a compact and cost-effective way. This paper reviews different photonic and electronic techniques for sub-THz and THz signal generation with implementation examples and discusses the future trends.
