Backscattering-Induced Dissipative Solitons in Ring Quantum Cascade Lasers
Lukas Seitner, Johannes Popp, Ina Heckelmann +5
Ring quantum cascade lasers have recently gained considerable attention, showing ultrastable frequency comb and soliton operation, thus opening a way to integrated spectrometers in…
Circuit quantum electrodynamic model of dissipative-dispersive Josephson traveling-wave parametric amplifiers
Yongjie Yuan, Michael Haider, Johannes A. Russer +2
We present a quantum mechanical model for a four-wave mixing Josephson traveling-wave parametric amplifier including substrate losses and associated thermal fluctuations. Under the…
Reducing the reflection error of PML absorbing boundary conditions within a generalized Maxwell-Bloch framework
Johannes Popp, Lukas Seitner, Michael Haider +1
We demonstrate a full-wave numerical Maxwell-Bloch simulation tool including perfectly matched layer (PML) absorbing boundary conditions. To avoid detrimental reflection errors at…
Controlling Domain-Wall Nucleation in Ta/CoFeB/MgO Nanomagnets via Local Ga+ Ion Irradiation
Simon Mendisch, Fabrizio Riente, Valentin Ahrens +6
Comprehensive control of the domain wall nucleation process is crucial for spin-based emerging technologies ranging from random-access and storage-class memories over domain-wall l…
Monte Carlo Modeling of Terahertz Quantum Cascade Detectors
Johannes Popp, Michael Haider, Martin Franckié +2
We demonstrate an Ensemble Monte Carlo (EMC) modeling approach for robust and rigorous simulations of photovoltaic quantum cascade detectors (QCDs) in the mid-infrared (mid-IR) and…
