Triple V-shaped type-II quantum wells for long wavelength interband cascade lasers
B. Petrović, T. Sato, S. Birner +5
We investigate triple V-shaped type-II quantum wells designed to emit at 6-9 μm wavelength range, consisting of three InAs(Sb) electron quantum wells and two Ga0.6In0.4Sb hole quan…
Quasiparticle picture of topological phase transitions induced by interactions
S. S. Krishtopenko, A. V. Ikonnikov, F. Hartmann +3
We present a general recipe to describe topological phase transitions in condensed matter systems with interactions. We show that topological invariants in the presence of interact…
5.0 m emitting Interband Cascade Lasers with Superlattice and Bulk AlGaAsSb Claddings
B. Petrović, A. Bader, J. Nauschütz +5
We present a comparison between interband cascade lasers (ICLs) with a 6-stage active region emitting at 5 m with AlSb/InAs superlattice claddings and with bulk Al_0.85 Ga_0.15…
GaSb-based Interband Cascade Laser with hybrid superlattice plasmon-enhanced claddings
B. Petrović, A. Bader, J. Nauschütz +5
We present an interband cascade laser (ICL) emitting at 5.2 μm consisting of an 8-stage active region and a hybrid cladding composed of outer plasmon-enhanced InAs_0.915 Sb_0.085 a…
Optical mapping of non-equilibrium charge carriers
E. David Guarin Castro, A. Pfenning, F. Hartmann +6
We investigate the energy relaxation segmentation in a resonant tunneling heterostructures by assessing the optical and transport dynamics of non-equilibrium charge carriers. The e…
