Impact of Carrier Injector Design on the Threshold of Interband Cascade Lasers
T. Sato, B. PetroviÄ, R. Weih +5
We theoretically investigate how the injector region design of interband cascade lasers (ICLs) impacts the threshold carrier and current densities. The model combines a polarizatio…
Resolving the band alignment of InAs/InAsSb mid-wave-infrared type-II superlattices
MichaÅ RygaÅa, Julian Zanon, Andreas Bader +5
In this work, three InAs/InAsSb superlattices with different periods were investigated using photoluminescence and photoreflectance measurements and their band st…
Oxide Interface-Based Polymorphic Electronic Devices for Neuromorphic Computing
Soumen Pradhan, Kirill Miller, Fabian Hartmann +9
Aside from recent advances in artificial intelligence (AI) models, specialized AI hardware is crucial to address large volumes of unstructured and dynamic data. Hardware-based AI,…
Triple V-shaped type-II quantum wells for long wavelength interband cascade lasers
B. PetroviÄ, 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 qua…
Comparison between InAs-based and GaSb-based Interband cascade lasers with hybrid superlattice plasmon-enhanced claddings
B. PetroviÄ, A. Bader, J. Nauschütz +6
We compare InAs-based and GaSb-based interband cascade lasers (ICLs) with the same 12 stages active region designed to emit at a wavelength of 4.6 μm. They employ a hybrid claddin…
