Quantum-mechanical wavepacket transport in quantum cascade laser structures
S. -C. Lee, F. Banit, M. Woerner +1
We present a viewpoint of the transport process in quantum cascade laser structures in which spatial transport of charge through the structure is a property of coherent quantum-mec…
Theoretical analysis of spectral gain in a THz quantum cascade laser: prospects for gain at 1 THz
S. -C. Lee, A. Wacker
In a recent Letter [Appl. Phys. Lett. 82, 1015 (2003)], Williams et al. reported the development of a terahertz quantum cascade laser operating at 3.4 THz or 14.2 meV. We have calc…
Simulation of Transport and Gain in Quantum Cascade Lasers
A. Wacker, S. -C. Lee, M. F. Pereira
Quantum cascade lasers can be modeled within a hierarchy of different approaches: Standard rate equations for the electron densities in the levels, semiclassical Boltzmann equation…
Gain and Loss in Quantum Cascade Lasers
A. Wacker, S. -C. Lee
We report gain calculations for a quantum cascade laser using a fully self-consistent quantum mechanical approach based on the theory of nonequilibrium Green functions. Both the ab…
Quantum transport calculations for quantum cascade laser structures
S. C. Lee, A. Wacker
We apply a quantum transport theory based on nonequilibrium Green's functions to quantum cascade laser (QCL) structures, treating simultaneously the transmission through the inject…
