Abstract

Ultrafast optical techniques provide a powerful means of investigating the dynamics of carrier transport and tunneling in semiconductor microstructures. We present a brief review of the basic concepts and various all-optical techniques. We then discuss our results on the direct determination of the dynamics of perpendicular transport using subpicosecond luminescence spectroscopy. Finally, we discuss our recent results on the direct determination of resonant and non-resonant tunneling times in asymmetric double quantum well structures.
