Abstract

We have measured carrier sweep-out times as a function of electric field applied perpendicular to GaAs/AlGaAs multiple quantum wells at different pump power levels in picosecond pump- probe experiments. Resonant tunneling was observed at 5V at low pump pulse energies. At higher excitation levels, the effects of space charge build-up were found to significantly alter the transient nonlinear optical response due to changes in the time constants associated with vertical carrier transport in the screened field.
