Optica terahertz
WebIn engineering, the terahertz gap is a frequency band in the THz region for which practical technologies for generating and detecting the radiation do not exist. It is defined as 0.1 to 10 THz ( wavelengths of 3 mm to 30 µm) although the upper boundary is somewhat arbitrary and is considered by some sources as 30 THz (a wavelength of 10 µm). [26]

Dynamic control of terahertz (THz) waves at-will with an ultracompact device is important for THz technologies in biomedical imaging, telecommunications, detection, and beyond. WebTogether with carrier acceleration in semiconductors and polymers, optical rectification is one of the main mechanisms for the generation of terahertz radiation using lasers. [5] This is different from other processes of terahertz generation such as polaritonics where a polar lattice vibration is thought to generate the terahertz radiation .
