Terahertz Radiation: Materials and Applications

About this Research Topic

Terahertz (THz) radiation is receiving increasing attention for its very diverse range of applications in both technology and science, including such areas as information and communications technology (ICT), non-destructive sensing and imaging, strong light-matter coupling, physics, and biology. Recent breakthroughs have further pushed THz research into center-stage with the development of high-power THz sources, e.g. THz quantum cascade lasers. The past 20 years have witnessed a revolution in THz technology, which is mainly driven by exploring diverse material systems.

Continual advances in THz technology rely on the state-of-the-art materials that meet the requirements of ultrafast dynamics, low loss, and miniaturization in high-frequency electronics and optics. Next-generation wireless communications would demand the frequency extension to the THz band. Thus, the development of devices in the THz band for high-speed communications such as antennas, waveguides, modulators, and detectors is urgent. This development is not only important for the understanding of optical physics in fundamental light-matter interactions but is also beneficial for all the potential THz applications.

This Research Topic will focus on progress in THz technology in the relevant areas of materials and applications, including but not limited to the following themes:
• Terahertz metamaterials and metasurfaces;
• 2D materials/hybrid materials for terahertz modulation;
• Photonic crystals and low loss terahertz waveguides;
• Photonic cavities for strong light-matter interactions;
• Terahertz sensing and imaging devices;
• Nonlinear materials for terahertz generation.


Keywords: Terahertz, Communications, Imaging, Waveguides, Coupling, Modulators, Sensors


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
