We review the present status of the rapidly developing field of semiconductor laser diodes
based on self-organized quantum dots (QDs). Several milestones have been achieved since …

The coherent optical response of semiconductors has been the subject of substantial
research over the last couple of decades. The interest has been motivated by unique …

We measure a dephasing time of several hundred picoseconds at low temperature in the
ground-state transition of strongly confined InGaAs quantum dots, using a highly sensitive …

The pure dephasing of the optical polarization and the corresponding line shape of
absorption spectra in small quantum dots due to the interaction of the exciton both with …

Single dot photoluminescence spectroscopy was used to study the homogeneous linewidth
Γ of the ground-state exciton in In 0.60 Ga 0.40 As/GaAs quantum dots as function of …

We measured the intrinsic ground-state exciton dephasing and population dynamics in
colloidal quasi-two-dimensional (2D) CdSe nanoplatelets at low temperature (5–50 K) using …

A compact variable all-optical buffer using semiconductor quantum dot (QD) structures is
proposed and analyzed. The buffering effect is achieved by slowing down the optical signal …

We report measurements of ultralong coherence in self-assembled quantum dots. Transient
four-wave mixing experiments at 5 K show an average dephasing time of 372 ps …

We present measurements and calculations of optical Rabi oscillations in the excitonic
ground-state transition of an InGaAs quantum dot ensemble at low temperature. Rabi …

Single-photon interference is observed on the ultranarrow long-term stable exciton
resonance of an individual semiconductor quantum dot. This interference is related to the …
