Abstract in another language
We study the coherent control of capture and transport processes in a quantum wire-quantum dot-system which is homogeneously excited by ultrafast laser pulses. Due to the carrier capture into the quantum dot a spatial profile of the carrier density in the wire region builds up exhibiting wave fronts moving away from the dot. In the presence of a dot with two or more bound levels wave fronts resulting from the capture into different states can clearly be distinguished. By using a pair of phase locked pulses the capture rates into different levels but also the spatio-temporal dynamics in the wire region can be coherently controlled.
