Frontiers in THz Photonic Devices

Terahertz (THz) radiation bridges the gap between microwave and optical wavelengths and is loosely defined as the frequency range from 0.1 to 10 THz. Imaging and sensing with THz electromagnetic radiation have already found applications in science and industry, such as security and safety screening, process monitoring, non-contact material characterization, medical, biological and pharmaceutical research. The THz frequency range further provides an enormous unlicensed bandwidth, which is being explored for high-speed short-range communications. Terahertz (THz) photonic devices are now exploiting emerging materials systems, while novel device designs utilize plasmonic effects, nanophotonics, and metamaterials. This special topic highlights and reviews cutting-edge THz photonic devices which have been revolutionized from the advances in the above research areas.
