InGaAs Quantum Dots Coupled to a Reservoir of Nonequilibrium Free Carriers

Autor: Vasily V. Temnov, Juan P. Martínez-Pastor, S. Dommers, Jordi Gomis-Bresco, Dieter Bimberg, U. Woggon, M. Laemmlin

Publikováno v: IEEE Journal of Quantum Electronics. 45:1121-1128

We discuss the impact of a 2D-charged carrier reservoir for high-speed optical amplification and modulated lasing in quantum dot (QD)-based devices by testing the amplification of short trains of high power, femtosecond optical pulses in an InGaAs QD

Observation of an unusual temperature dependence of the initial decoherence time in quantum dots

Autor: Wolfgang Werner Langbein, Paola Borri, Alexei Vagov, Vollrath M. Axt, Tilmann Kuhn, U. Woggon

Publikováno v: physica status solidi (c). 2:3167-3170

We report on four-wave-mixing experiments in self-assembled InAs/GaAs quantum dots and compare with a theory that accounts for the pure-dephasing induced by acoustic phonons. The measurements demonstrate an unusual non-monotonous temperature dependen

Optical Properties of AgI Quantum Dots Embedded in a Glass Matrix

Autor: G. Mshvelidse, O. Gogolin, E. Tsitsishvili, Ch. Märkle, J.S. Chadha, A. Hepting, F. Gindele, W. Petri, W. Send, D. Gerthsen, U. Woggon, C. Klingshirn

Publikováno v: physica status solidi (b). 207:369-376

We report the fabrication, transmission electron microscopy investigation and linear optical properties of silver iodide quantum dots in an aluminaborosilicate host network structure. The nearly spherical quantum dots with radii ranging from 1.7 to 2
