Strategies for the alignment of electronic states in quantum-dot tunnel-injection lasers and their influence on the emission dynamics
Michael Lorke, Igor Khanonkin, Stephan Michael +3
In quantum-dot tunnel-injection lasers, the excited charge carriers are efficiently captured from the bulk states via an injector quantum well and then transferred into the quantum…
Carrier dynamics in quantum-dot tunnel-injection structures: microscopic theory and experiment
Michael Lorke, Igor Khanonkin, Stephan Michael +3
Tunneling-injection structures are incorporated in semiconductor lasers in order to overcome the fundamental dynamical limitation due to hot carrier injection by providing a carrie…
Performance of quantum-dot-based tunnel-injection lasers: A theoretical analysis
Michael Lorke, Stephan Michael, Marian Cepok +1
Tunnel-injection lasers promise advantages in modulation bandwidth and temperature stability in comparison to conventional laser designs. In this paper, we present results of a mic…
Group-velocity slowdown in a double quantum-dot molecule
Stephan Michael, Weng W. Chow, Hans Christian Schneider
The slowdown of optical pulses due to quantum-coherence effects is investigated theoretically for an "active material" consisting of InGaAs-based double quantum-dot molecules. Thes…
Group-velocity slowdown in quantum-dots and quantum-dot molecules
Stephan Michael, Weng W. Chow, Hans Christian Schneider
We investigate theoretically the slowdown of optical pulses due to quantum-coherence effects in InGaAs-based quantum dots and quantum dot molecules. Simple models for the electroni…
