Journal ArticleDOI
Ultralong Dephasing Time in InGaAs Quantum Dots
Paola Borri,Wolfgang Werner Langbein,S. Schneider,Ulrike Woggon,Roman Sellin,D. Ouyang,Dieter Bimberg +6 more
TL;DR: Between 7 and 100 K the polarization decay has two distinct components resulting in a non-Lorentzian line shape with a lifetime-limited zero-phonon line and a broadband from elastic exciton-acoustic phonon interactions.
Journal ArticleDOI
Rabi oscillations in the excitonic ground-state transition of InGaAs quantum dots
Paola Borri,Wolfgang Werner Langbein,S. Schneider,Ulrike Woggon,Roman Sellin,D. Ouyang,Dieter Bimberg +6 more
TL;DR: In this article, measurements and calculations of optical Rabi oscillations in the excitonic ground-state transition of an InGaAs quantum dot ensemble at low temperature are presented.
Journal ArticleDOI
Control of fine-structure splitting and biexciton binding in In x Ga 1 − x As quantum dots by annealing
Wolfgang Werner Langbein,Paola Borri,Ulrike Woggon,V. Stavarache,Dirk Reuter,Andreas D. Wieck +5 more
TL;DR: In this article, the distribution of the fine-structure splitting and the biexciton binding energy were measured in a series of annealed InAs quantum dots, and the authors found a decrease of the binding energy with increasing annealing temperature, indicating a symmetrizing of the in-plane confinement potential.
Journal ArticleDOI
Spectral hole-burning and carrier-heating dynamics in InGaAs quantum-dot amplifiers
Paola Borri,Wolfgang Werner Langbein,Jørn Märcher Hvam,Frank Heinrichsdorff,Ming-Hua Mao,Dieter Bimberg +5 more
TL;DR: In this paper, the spectral hole-burning and carrier heating were investigated in detail in a set of InAs-InGaAs-GaAs quantum-dot (QD) amplifiers with femtosecond resolution.
Journal ArticleDOI
Ultrafast gain dynamics in InAs-InGaAs quantum-dot amplifiers
Paola Borri,Wolfgang Werner Langbein,Jørn Märcher Hvam,Frank Heinrichsdorff,Ming-Hua Mao,Dieter Bimberg +5 more
TL;DR: In this paper, the ultrafast dynamics of gain and refractive index in an electrically pumped InAs-InGaAs quantum-dot (QD) optical amplifier are measured at room temperature using differential transmission with femtosecond time resolution.
