Generation of THz vector and scalar vortex beams by optical rectification along threefold symmetry axis in zinc blende crystals

Synthesis of THz frequency fields with generalized orbital angular momentum, the so called higher-order Poincaré beams are of interest to future communications systems and charged particle accelerators. We propose and demonstrate a route to generate and manipulate THz vector and scalar vortex beams...
