Nonlinear switching of low-index defect modes in photonic lattices
Fangwei Ye, Yaroslav V. Kartashov, Victor A. Vysloukh +1
We address nonlinear signal switching between two low-index defect channels induced in periodic optical lattices. In contrast to conventional directional couplers, where the guidin…
Bragg guiding of domain-like nonlinear modes and kink arrays in lower-index core structures
Fangwei Ye, Yaroslav V. Kartashov, Victor A. Vysloukh +1
We introduce a novel class of stable nonlinear modes trapped in a lower-index film core sandwiched between two optical lattices, or in the cylindrical core of a radial lattice, imp…
Stabilization of dipole solitons in nonlocal nonlinear media
Fangwei Ye, Yaroslav V. Kartashov, Lluis Torner
We address the stabilization of dipole solitons in nonlocal nonlinear materials by two different approaches. First, we study the properties of such solitons in thermal nonlinear me…
Nonlocal surface dipoles and vortices
Fangwei Ye, Yaroslav V. Kartashov, Lluis Torner
We predict the existence and address the stability of two-dimensional surface solitons featuring topologically complex shapes, including dipoles, vortices, and bound states of vort…
