A python package for ultrashort optical pulse propagation in terms of forward models for the analytic signal
O. Melchert, A. Demircan
We present a flexible, open-source Python package for the accurate simulation of the -propagation dynamics of ultrashort optical pulses in nonlinear waveguides, especially valid…
Domain Decomposition with Neural Network Interface Approximations for time-harmonic Maxwell's equations with different wave numbers
T. Knoke, S. Kinnewig, S. Beuchler +3
In this work, we consider the time-harmonic Maxwell's equations and their numerical solution with a domain decomposition method. As an innovative feature, we propose a feedforward…
Universal properties of locally generated terahertz waveforms from polarization-controlled two- and multi-color ionizing fields
H. Alirezaee, S. Skupin, V. Vaicaitis +4
The polarization states of terahertz (THz) radiation generated in a photo-ionized gas driven by strong two- or multi-frequency fields with locally controlled polarization are studi…
Isotopic variations and Zeeman-like splitting in the spectra of nonlinear photonic meta-atoms
S. Zhang, I. Babushkin, U. Morgner +2
We study photonic meta-atoms, a unique class of composite solitary wave, supported in nonlinear waveguides. We establish an analogy to one-dimensional soft-core atoms, allowing to…
A generalized nonlinear Schrödinger Python module implementing different models of input pulse quantum noise
O. Melchert, A. Demircan
We provide Python tools enabling numerical simulation and analysis of the propagation dynamics of ultrashort laser pulses in nonlinear waveguides. The modeling approach is based on…
Terahertz and higher-order Brunel harmonics: from tunnel to multiphoton ionization regime in tailored fields
I. Babushkin, C. Brée, C. M. Dietrich +3
Brunel radiation appears as a result of a two-step process of photo-ionization and subsequent acceleration of electron, without the need of electron recollision. We show that for g…
