Abstract
We report optical coherent control of the emission direction of THz radiation by excitation of bulk GaAs with femtosecond laser pulses. Changing the phase of the optical excitation, steering angles of ~8 degrees are realized. A simple model is introduced to analyze the underlying parameters.
