Summary form only given. When intersubband transitions are excited in semiconductor heterostructures, the charge carriers follow the driving field in an oscillatory motion. THz time-domain spectroscopy is an attractive tool to study the polarization following an exciting THz pulse. A time resolution which is shorter than the oscillation time of the driving field enables the observation of the coherent electron motion for the first time. The investigated GaAs/AlGaAs heterostructures are modulation doped parabolic quantum wells.
