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…
Two-color soliton meta-atoms and molecules
O. Melchert, S. Willms, I. Babushkin +2
We present a detailed overview of the physics of two-color soliton molecules in nonlinear waveguides, i.e. bound states of localized optical pulses which are held together due to a…
Soliton compression and supercontinuum spectra in nonlinear diamond photonics
O. Melchert, S. Kinnewig, F. Dencker +9
We numerically explore synthetic crystal diamond for realizing novel light sources in ranges which are up to now difficult to achieve with other materials, such as sub-10-fs pulse…
Resonant Kushi-comb-like multi-frequency radiation of oscillating two-color soliton molecules
O. Melchert, S. Willms, I. Oreshnikov +4
Nonlinear waveguides with two distinct domains of anomalous dispersion can support the formation of molecule-like two-color pulse compounds. They consist of two tightly bound subpu…
Cherenkov radiation and scattering of external dispersive waves by two-color solitons
Ivan Oreshnikov, Oliver Melchert, Stephanie Willms +5
For waveguides with two separate regions of anomalous dispersion, it is possible to create a quasi-stable two-color solitary wave. In this paper we consider how those waves interac…
High order Brunel harmonics and supercontinuum formed by a weak optical pump in presence of a strong terahertz field
Ihar Babushkin, Ayhan Demircan, Uwe Morgner +1
Brunel harmonics appear in the optical response of an atom in process of laser-induced ionization, when the electron leaves the atom and is accelerated in the strong optical field.…
