Paper Abstract
Intense terahetz (THz) pulses induce a photoluminescence (PL) flashes from undoped GaAs/AlGaAs quantum wells under continuous wave laser excitation. The number of excitons increases 10000-fold from that of the steady state. The THz electric field dependence and the relaxation dynamics of the PL flash intensity suggest that the strong electric field of the THz pulse ionizes trap states during the one-picosecond period of the THz pulse and release carriers existing in a giant reservoir containing many trap states in the AlGaAs layers.
