Abstract
Abstract We present a two‐colour photocurrent detection method for coherent control of a single InGaAs/GaAs self‐assembled quantum dot. A pulse shaping technique provides a high degree of control over picosecond optical pulses. Rabi rotations on the exciton to biexciton transition are presented, and fine structure beating is detected via time‐resolved measurements. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
