Two-color surface lattice solitons
Zhiyong Xu, Yuri S. Kivshar
We study the properties of surface solitons generated at the edge of a semi-infinite photonic lattice in nonlinear quadratic media, namely two-color surface lattice solitons. We an…
Rotating surface soliton complexes in annular waveguides
Zhiyong Xu
We address surface soliton complexes formed at the edge of annular guiding structures containing several concentric rings. Such soliton complexes feature a -phase difference betwee…
Nonlinear photonic crystals near the supercollimation point
Zhiyong Xu, Bjorn Maes, Xunya Jiang +3
We uncover a strong coupling between nonlinearity and diffraction in a photonic crystal at the supercollimation point. We show this is modeled by a nonlinear diffraction term in a…
Two-dimensional multi-pole solitons in nonlocal nonlinear media
Carmel Rotschild, Zhiyong Xu, Oren Cohen +3
We present the experimental observation of scalar multi-pole solitons in highly nonlocal nonlinear media, including dipole-, tri-pole, quadru-pole, and necklace-type solitons, orga…
