Journal ArticleDOI
A new class of integrable systems and its relation to solitons
TL;DR: In this paper, a class of finite-dimensional integrable systems that may be viewed as relativistic generalizations of the Calogero-Moser systems were studied.
Journal ArticleDOI
Thermionic emission and Gaussian transport of holes in a GaAs/AlxGa1-xAs multiple-quantum-well structure.
TL;DR: A modified thermionic emission model for time-resolved charge-carrier transport perpendicular to the layers of multiple quantum-well structures in an electric field agrees favorably with experiments performed for the case of holes and allows an accurate determination of the band offset.
Journal ArticleDOI
Carrier Relaxation in Epitaxial Graphene Photoexcited Near the Dirac Point
Stephan Winnerl,Milan Orlita,Milan Orlita,Paulina Plochocka,Piotr Kossacki,Marek Potemski,Torben Winzer,Ermin Malic,Andreas Knorr,Mike Sprinkle,Claire Berger,W. A. de Heer,Harald Schneider,Manfred Helm +13 more
TL;DR: The experiments complemented by microscopic modeling reveal that the carrier relaxation is significantly slowed down as the photon energy is tuned to values below the optical-phonon frequency; however, owing to the presence of hot carriers, optical-Phonon emission is still the predominant relaxation process.
Journal ArticleDOI
Multimode regimes in quantum cascade lasers: From coherent instabilities to spatial hole burning
Ariel Gordon,C. Y. Wang,Laurent Diehl,Franz X. Kärtner,Alexey Belyanin,David P. Bour,Scott W. Corzine,Gloria E Hofler,H. C. Liu,Harald Schneider,Thomas Maier,Mariano Troccoli,Jérôme Faist,Federico Capasso +13 more
TL;DR: In this paper, a theoretical and experimental study of multimode operation regimes in quantum cascade laser (QCLs) is presented and a model that can account for coherent phenomena, a saturable absorber, and SHB is developed and studied in detail both analytically and numerically.
Journal ArticleDOI
Mode-locked pulses from mid-infrared quantum cascade lasers.
C. Y. Wang,Lyuba Kuznetsova,Vasileios-Marios Gkortsas,Laurent Diehl,Franz X. Kärtner,Mikhail A. Belkin,Alexey Belyanin,Xiaofeng Li,Donhee Ham,Harald Schneider,P. D. Grant,C. Y. Song,Soufien Haffouz,Z. R. Wasilewski,H. C. Liu,Federico Capasso +15 more
TL;DR: This study reports the unequivocal demonstration of midinfrared mode-locked pulses from quantum cascade lasers generated by actively modulating the current and hence the gain of an edge-emitting quantum cascade laser (QCL).
