Interface solitons in quadratically nonlinear photonic lattices
Zhiyong Xu, Mario I. Molina, Yuri S. Kivshar
We study the properties of two-color nonlinear localized modes which may exist at the interfaces separating two different periodic photonic lattices in quadratic media, focussing o…

Spatial-Spectral Vortex Solitons in Quadratic Lattices
Zhiyong Xu, Andrey A. Sukhorukov
We predict the existence of spatial-spectral vortex solitons in one-dimensional periodic waveguide arrays with quadratic nonlinear response. In such vortices the energy flow forms…
