Terahertz radiation – also known as submillimeter radiation, terahertz waves, tremendously high frequency [1] (THF), T-rays, T-waves, T-light, T-lux or THz – consists of electromagnetic waves within the International Telecommunication Union-designated band of frequencies from 0.1 to 10 terahertz (THz), [2] (from 0.3 to 3 terahertz (THz) in ...

2025年1月9日 · In the terahertz (THz) region, various approaches have been independently demonstrated to optimize the nonlinear effects in graphene, addressing a critical limitation arising from the...

2024年6月25日 · Terahertz modulators play a critical role in high-speed wireless communication, non-destructive imaging, and so on, which have attracted a large amount of research interest. Nevertheless,...

2025年2月24日 · The interaction between terahertz (THz) frequency light and matter has been a mostly neglected research area for a long time, until ground-breaking advances in the technology to generate, detect, and manipulate THz frequency beams were achieved.

2019年12月12日 · Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and collective excitations in solids, to drive phase transitions and associated changes in material properties, and to study rotations and vibrations in molecular systems.

2024年8月16日 · Here, we propose a metallic THz photonic crystal resonator with a phase-engineered design for single mode surface emission over a broad area. The quantum cascade surface-emitting laser is capable...

2025年3月7日 · In the current work, we present a theoretical and computational investigation on terahertz (THz) light-induced phase transformation of conventional binary semiconducting compounds among different structures including rock …

3 天之前 · The THz-light-field-driven, ultrafast USMR effect enabled magnetization states to be detected through the direct measurement of the electrical field from the second harmonic generation (SHG) signal. At THz frequencies, USMR thus enabled readouts in ps, initiated by the light fields. The researchers observed ultrafast USMR in the thin film ...

2025年2月16日 · Here, a polymer-silicon heterostructure is proposed as a THz SLM using continuous-wave (CW) optical illumination. The organic-semiconductor interface promotes photo-generated carrier accumulation, while the thickness of the silicon substrate influences the whole effective carrier lifetime.

6 天之前 · Terahertz waves inhabit a neglected section of the electromagnetic spectrum between microwaves and far infrared light, usually in the range of 0.1 to 10 terahertz.
