Impact ionization dynamics in small band-gap 2D materials from a coherent phonon mechanism
Stephan Michael, Hans Christian Schneider
We study theoretically the role of carrier multiplication due to impact ionization after an ultrafast optical excitation in a model system of a quasi-two dimensional material with…
Carrier Dynamics in a Tunneling Injection Quantum Dot Semiconductor Optical Amplifier
I. Khanonkin, M. Lorke, S. Michael +4
The process of tunneling injection is known to improve the dynamical characteristics of quantum well and quantum dot lasers; in the latter, it also improves the temperature perform…
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…
Interplay of structural design and interaction processes in tunnel-injection semiconductor lasers
Stephan Michael, Michael Lorke, Marian Cepok +2
Tunnel-injection lasers promise various advantages in comparison to conventional laser designs. In this paper, we present a theoretical analysis for the physics of the tunnel-injec…
