摘要
ABSTRACT
This talk presents how effectively photonics technologies are implemented not only in generation, detection and transmission of continuous terahertz (THz) waves, but also in system applications such as communications, measurements, spectroscopy and imaging, in order to efficiently enhance their performance. After briefly reviewing key devices and components, first, wireless communications applications are discussed aiming at a data rate of terabit/s. Next, applications to measurement and sensing are explained, and as most recent examples, visualization of THz electric-field radiation and propagation, and THz information tags are presented. Finally, in order to make THz systems more compact and cost-effective, recent challenges in photonic integration technologies are described, which include monolithically integrated photonic signal generators, and hybrid integration schemes using, for instance, photonic crystal and related dielectric material platforms.
