Abstract

We demonstrate the ultrafast coherent dynamics of exciton wavepackets in semiconductor QWs resonantly driven by strong narrowband THz pulses. Time-resolved THz-pump and optical-probe measurements exhibit large-signal nonlinear optical transients of the HH and LH exciton lines in GaAs/AlGaAs QWs.
