Photon-induced carrier transport in high efficiency midinfrared quantum cascade lasers
Photon-induced carrier transport midinfrared quantum cascade lasers Optics
2011/8/18
Abstract: A midinfrared quantum cascade laser with high wall-plug efficiency is analyzed by means of an ensemble Monte Carlo method. Both the carrier transport and the cavity field dynamics are includ...
Temperature performance analysis of terahertz quantum cascade lasers: Vertical versus diagonal designs
Temperature performance analysis terahertz quantum cascade lasers Vertical versus diagonal designs
2011/9/14
Resonant phonon depopulation terahertz quantum cascade lasers based on vertical and diagonal lasing transitions are systematically compared using a well established ensemble Monte-Carlo approach. The ...
Modeling bound-to-continuum terahertz quantum cascade lasers: The role of Coulomb interactions
Modeling bound-to-continuum terahertz quantum cascade lasers Coulomb interactions
2011/9/14
Based on an ensemble Monte Carlo analysis, we show that Coulomb interactions play a dominant role in boundto-continuum terahertz quantum cascade lasers and thus require careful modeling. Coulomb inter...

2011/9/14
Employing an ensemble Monte Carlo transport simulation, we self-consistently analyze the spectral gain for different THz quantum cascade laser structures, considering bound-to-continuum as well as res...
Monte Carlo study of carrier-light coupling in terahertz quantum cascade lasers
Monte Carlo carrier-light coupling terahertz quantum cascade lasers
