Webb9 nov. 2024 · The Terahertz (THz) band from 0.1 THz to 10 THz will be of paramount importance for wireless communications in the next decade. In particular, due to its abundant frequency resources, the THz band will be a key to overcome the spectrum scarcity and capacity limitations inherent to curre nt wireless systems. Typically, an ultrashort pulsed laser is used in the terahertz pulse generation process. In the use of low-temperature grown GaAs as an antenna, the ultrashort pulse creates charge carriers that are accelerated to create the terahertz pulse. In the use of non-linear crystals as a source, a high-intensity ultrashort pulse produces THz radiation from the crystal. A single terahertz pulse can contain frequency components covering much of the terahertz range, often from 0.05 to 4 THz, th…
