Abstract

We measured the transient absorption changes of a near-infrared (NIR) pulse in GaAs quantum well under a multicycle THz wave driving. By changing the delay between the NIR probe and the THz wave, the absorption strength can be modulated on a sub-cycle timescale of THz wave, indicating the formation of THz-induced dressed states of excitons.
