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…

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…
