182nd Committee on Terahertz Science, Technology and Industrial Development

Goals

Developments related to terahertz frequencies are anticipated in a wide range of fields, including those related to materials, bio-medicine, and safety and crime prevention (security), because terahertz frequencies can be used to find important information about the physical properties of matter and organisms. Vigorous research is being conducted on device development. Applications for cutting-edge measurement and analysis technologies, such as sensing and imaging, are using terahertz frequencies. Commercial, general-purpose, and medical analysis products are also becoming available now. With these hopes for the future innovation of the field of terahertz wave technology, vanguard academic and industrial researchers and engineers in the fields of terahertz wave, quantum physics and electronics, molecular chemistry, medicine, and pharmacology exchange information among organizations and disciplines to promote joint research. They are unearthing basic technologies, and also attempting to create new industries that utilize the characteristics of unexplored electromagnetic waves.


Research Themes

Research fields on which the committee focuses its discussions include the information and communication technology sector, providing wireless solutions for broadband networks; the security sector, realizing safety and security in society with technologies to detect concealed items; and the biology and medical sectors, employing spectroscopic technologies that interact with organic molecules.

Specifically, we decided to conduct research on four technologies—terahertz source and detection devices, spectroscopy, imaging, and other terahertz-related areas. Themes include difference-frequency-mixing terahertz wave generation, solid-state terahertz oscillators such as Gunn oscillators, IMPATT oscillators, TUNNET diodes and resonant tunneling diodes, spectroscopy and imaging systems that employ photoconductive antennae and non-linear optical crystals, quantum cascade and p-germanium lasers, gyrotrons, free-electron lasers, and terahertz wave detection devices such as thermal, quantum, superconducting and antenna coupled detectors.
