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…

SWtools: A Python module implementing iterative solvers for soliton solutions of nonlinear Schrödinger-type equations
O. Melchert, A. Demircan
Solitons are ubiquitous in nature and play a pivotal role in the structure and dynamics of solutions of nonlinear propagation equations. In many instances where solitons exist, ana…

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…
