Review on Photoconductive Antenna Design from Conventional to Microstructures
Abstract: Semiconductors possess many diverse phenomena under terahertz-frequency electromagnetic radiation (THz). This is due to the fact that the energy of THz photons is at quite large scales in case of bulk and low-dimensional materials and devices. With regard to broadband THz sources, various inorganic crystals such as ZnTe/GaP/GaAs/GaSe/DAST/LiNbO3 have been used which are pumped by femtosecond laser pulses. These pulses are combined with field-resolved detection through electro-optic sampling using similar …
