Prospect for Terahertz Technology

Terahertz Technology

Terahertz technology applications, sensors, and sources are briefly reviewed. Emphasis is placed on the less familiar components, instruments, or subsystems. Science drivers, some historic background, and future trends are also discussed.

Terahertz Technology for Nano Applications

The terahertz (THz) region of the electromagnetic spectrum is generally defined as the frequency range of 0.1–10 THz (10 cycles per second) corresponding to quantum energy of 0.4 meV–0.4 eV (see Fig. 1). THz electromagnetic waves (also known as T-rays) have several properties that could promote their use as sensing and imaging tool. There is no ionization hazard for biological tissue and Raylei...

Cutting-edge terahertz technology

Terahertz (THz) radiation, which lies in the frequency gap between the infrared and microwaves, typically referred to as the frequencies from 100 GHz to 30 THz, has long been studied in fields such as astronomy and analytical science. However, recent technological innovation in photonics and nanotechnology is now enabling THz research to be applied in many more sectors. Today, THz technology is...
