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…
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.…
Metallic nanostructures as electronic billiards for nonlinear terahertz photonics
Ihar Babushkin, Liping Shi, Ayhan Demircan +3
Optical properties of metallic nanoparticles are most often considered in terms of plasmons, the coupled states of light and quasi-free electrons. Here we predict that confinement…
Dynamic focus shaping with mixed-aperture coherent beam combining
Maike Prossotowicz, Daniel Flamm, Andreas Heimes +5
A novel concept for dynamic focus shaping based on highly efficient coherent beam combining with microlens arrays (MLA) as combining element is presented. This concept allows to co…
