Abstract :
Summary form only given. The spectroscopy of individual quantum dots (QDs) using optical micro-probing techniques is opening up possibilities of various applications based on the physics of the zero-dimensional (0D) semiconductor structures. Self-assembled quantum dots (SAQDs) are also attractive 0D structures, where strong confinement on a no-meter scale can be realized. Here, we carried out time-correlation measurements of excited carriers in single SAQDs in order to realize coherent optical control. The sharpness of the resonance lines in single dot photoluminescence allows us to observe a long phase relaxation time.
