We proposed and demonstrated active control of terahertz optical activity via chiral patterned photoexcitation in a semiconductor with a spatial light modulator (SLM). Arbitrary patterns can be generated by a SLM, including completely symmetric enantiomer pairs. This technique provides a new route to terahertz polarization modulators.
