A Theory of Nested Cascading in Directed Logic
Ihar Babushkin, Oliver Melchert, Ayhan Demircan +1
In directed logic (DL), electronically controlled optical elements serve as photonic gates. Such electro-optical elements are of mixed nature: they have two inputs--electronic and…
Photocurrent-induced harmonics in nanostructures
Ihar Babushkin, Anton Husakou, Liping Shi +3
Photocurrent-induced harmonics appear in gases and solids due to tunnel ionization of electrons in strong fields and subsequent acceleration. In contrast to three-step harmonic emi…
Optical Solitary Wavelets
O. Melchert, A. Demircan
We investigate wavelet-like localized solutions in nonlinear waveguides, enabled by complementary propagation constants embedded in domains of anomalous dispersion. They are carrie…
Mathematical modeling and numerical multigoal-oriented a posteriori error control and adaptivity for a stationary, nonlinear, coupled flow temperature model with temperature dependent density
Sven Beuchler, Ayhan Demircan, Bernhard Endtmayer +2
In this work, we develop adaptive schemes using goal-oriented error control for a highly nonlinear flow temperature model with temperature dependent density. The dual-weighted resi…
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…
Wave-Shape-Tolerant Photonic Quantum Gates
Ihar Babushkin, Ayhan Demircan, Michael Kues +1
Photons, acting as ``flying qubits'' in propagation geometries such as waveguides, appear unavoidably in the form of wavepackets (pulses). The actual shape of the photonic wavepack…
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…
OptFROG - Analytic signal spectrograms with optimized time-frequency resolution
O. Melchert, B. Roth, U. Morgner +1
A Python package for the calculation of spectrograms with optimized time and frequency resolution for application in the analysis of numerical simulations on ultrashort pulse propa…
