A terahertz pulse shaper based on optical rectification is proposed. The polarization of the terahertz pulses depends on the polarization selection rules for the rectification process in a GaP crystal. The terahertz pulse shaper can arbitrarily control the chirality, phase, pulse duration and frequency of circularly polarized few-cycle terahertz pulses.
