Journal ArticleDOI
Mid-infrared semiconductor heterostructure lasers for gas sensing applications
TL;DR: An overview of the three competing mid-infrared semiconductor laser approaches, being diode, quantum cascade and interband cascade laser designs, is given in this paper, where the authors discuss the limiting factors as well as unique possibilities of each approach.
Journal ArticleDOI
Control of the Strong Light-Matter Interaction between an Elongated In 0.3 Ga 0.7 As Quantum Dot and a Micropillar Cavity Using External Magnetic Fields
Stephan Reitzenstein,S. Munch,P. Franeck,A. Rahimi-Iman,Andreas Löffler,Sven Höfling,L. Worschech,Alfred Forchel +7 more
TL;DR: A transition from strong coupling towards the critical coupling regime is attributed to a reduction of the quantum dot oscillator strength when the magnetic confinement becomes significant with regards to the exciton confinement above 3 T.
Journal ArticleDOI
Continuous-wave operation of type-I quantum well DFB laser diodes emitting in 3.4 μm wavelength range around room temperature
L. Naehle,Sofiane Belahsene,M. von Edlinger,M. Fischer,Guilhem Boissier,Pierre Grech,G. Narcy,Aurore Vicet,Yves Rouillard,J. Koeth,L. Worschech +10 more
TL;DR: In this paper, a distributed feedback (DFB) laser diodes based on the concept of lateral metal gratings fabricated on type-I quantum well GaInAsSb/AlGaInSb material are presented.
Journal ArticleDOI
Universal and reconfigurable logic gates in a compact three-terminal resonant tunneling diode
L. Worschech,Fabian Hartmann,T. Y. Kim,Sven Höfling,M. Kamp,Alfred Forchel,Jouni Ahopelto,Igor Neri,Anna Dari,Luca Gammaitoni +9 more
TL;DR: In this article, resonant tunneling diodes (RTDs) with split drain contacts have been realized and the current-voltage characteristics have been studied in the bistable regime at room temperature.
Journal ArticleDOI
Experimental Verification of the Very Strong Coupling Regime in a GaAs Quantum Well Microcavity.
Sebastian Brodbeck,S. De Liberato,M. Amthor,Martin Klaas,Martin Kamp,L. Worschech,Christian Schneider,Sven Höfling,Sven Höfling +8 more
TL;DR: This work verifies the existence of the very strong coupling regime in magneto-optical measurements on a microcavity characterized by g/E_{B}≈0.64, showing that the average electron-hole separation of the upper polariton is significantly increased compared to the bare quantum well exciton Bohr radius.
