Second order nonlinear optical processes in  cubic crystals for terahertz optoelectronics
Keywords: THz optoelectronics
AbstractIn this paper, we give an overview of emission and detection of terahertz electromagnetic pulses using, respectively, optical rectification and electro-optic effect in  zinc blende crystals. This crystal orientation allows us to generate and read any polarization state of the THz beam only by controlling the polarization state of the laser beam that excites or probes the emitting and receiving crystals. This technique is very useful for polarimetric terahertz spectroscopic studies.
