Bright Discrete Solitons in Spatially Modulated DNLS Systems
P. G. Kevrekidis, R. L. Horne, N. Whitaker +2
In the present work, we revisit the highly active research area of inhomogeneously nonlinear defocusing media and consider the existence, spectral stability and nonlinear dynamics…
Asymmetric Wave Propagation Through Saturable Nonlinear Oligomers
Daniel Law, Jennie D'Ambroise, Panayotis G. Kevrekidis +1
In the present paper we consider nonlinear dimers and trimers (more generally, oligomers) embedded within a linear Schr{ö}dinger lattice where the nonlinear sites are of saturable…
Dark lattice solitons in one-dimensional waveguide arrays with defocusing saturable nonlinearities and alternating couplings
Andrey Kanshu, Christian E. Rüter, Detlef Kip +2
In the present work, we examine "binary" waveguide arrays, where the coupling between adjacent sites alternates between two distinct values and and a saturable nonlinea…
Dark-bright gap solitons in coupled-mode one-dimensional saturable waveguide arrays
Rong Dong, Christian E. Rüter, Detlef Kip +4
In the present work, we consider the dynamics of dark solitons as one mode of a defocusing photorefractive lattice coupled with bright solitons as a second mode of the lattice. Our…
Saturable discrete vector solitons in one-dimensional photonic lattices
Rodrigo A. Vicencio, Eugene Smirnov, Christian E. Rüter +2
Localized vectorial modes, with equal frequencies and mutually orthogonal polarizations, are investigated both analytically and experimentally in a one-dimensional photonic lattice…
Tamm oscillations in semi-infinite nonlinear waveguide arrays
Milutin Stepić, Christian E. Rüter, Eugene Smirnov +3
We demonstrate numerically the existence of nonlinear Tamm oscillations at the interface between a substrate and one-dimensional waveguide array with both cubic and saturable, self…
