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…
Ultrashort pulse generation from a graphene-coupled passively mode-locked terahertz laser
Elisa Riccardi, Valentino Pistore, Seonggil Kang +10
The generation of stable trains of ultra-short (fs-ps), terahertz (THz)-frequency radiation pulses, with large instantaneous intensities, is an underpinning requirement for the inv…
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…
