Low-threshold operation of GaAs-based (GaIn)As/Ga(AsSb)/(GaIn)As W-quantum well lasers emitting in the O-band
Christian Fuchs, Imad Limame, Stefan Reinhard +6
The influence of the growth conditions as well as the device design on the device performance of (GaIn)As/Ga(AsSb)/(GaIn)As "W"-quantum well lasers is investigated. To this purpose…
Extension of the LDA-1/2 method to the material class of bismuth containing III-V semiconductors
Sven C. Liebscher, Lars C. Bannow, Jörg Hader +2
The LDA-1/2 method is employed in density functional theory calculations for the electronic structure of III-V dilute bismide systems. For the representative example of Ga(SbBi) wi…
Mode-locking in vertical external-cavity surface-emitting lasers with type-II quantum-well configurations
I. Kilen, S. W. Koch, J. Hader +1
A microscopic study of mode-locked pulse generation is presented for vertical external-cavity surface-emitting lasers utilizing type-II quantum well configurations. The coupled Max…
Ultrafast band-gap renormalization and build-up of optical gain in monolayer MoTe
Lars Meckbach, Jörg Hader, Josefine Neuhaus +5
The dynamics of band-gap renormalization and gain build-up in monolayer MoTe is investigated by evaluating the non-equilibrium Dirac-Bloch equations with the incoherent carrier…
Microscopic calculation of the optical properties and intrinsic losses in the methylammonium lead iodide perovskite system
Lars C. Bannow, Jörg Hader, Jerome V. Moloney +1
For opto-electronic and photo-voltaic applications of perovskites, it is essential to know the optical properties and intrinsic losses of the used materials. A systematic microscop…
Non-equilibrium dynamics in the dual-wavelength operation of Vertical external-cavity surface-emitting lasers
I. Kilen, J. Hader, S. W. Koch +1
Microscopic many-body theory coupled to Maxwell's equation is used to investigate dual-wavelength operation in vertical external-cavity surface-emitting lasers. The intrinsically d…
