摘要：
We report femtosecond pump-probe transmission spectroscopy experiments on GaAs/AlGaAs asymmetric-coupled quantum wells, using a spectrally narrow optical excitation at 740 nm. The time-resolved evolution of the bleaching demonstrates the tunneling of both carriers through the barrier. At high densities a single tunneling time is observed in opposition to the low density regime, where the electron and hole contributions are well separated.
