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…
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…
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…
