Saddle solitons: a balance between bi-diffraction and hybrid nonlinearity.

چکیده
We demonstrate self-trapping of light by simultaneously compensating normal and anomalous (saddle-shaped) diffractions with self-focusing and self-defocusing hybrid nonlinearity in optically induced ionic-type photonic lattices. Innovative two-dimensional gap solitons, named "saddle solitons," are established, whose phase and spectrum characteristics are different from all previously observed spatial solitons.

Spatial dark optical solitons are localized light intensity dips in the infinite constant background [1–3]. Like their bright counterparts, they propagate preserving their spatial profile. This is a result of a balance between diffraction which tends to broaden their size and nonlinearity of the medium which counteracts this process. The existence of dark spatial solitons requires the nonlinear...
متن کاملThree-dimensional vortex solitons in self-defocusing media.
We demonstrate that families of vortex solitons are possible in a bidispersive three-dimensional nonlinear Schrödinger equation. These solutions can be considered as extensions of two-dimensional dark vortex solitons which, along the third dimension, remain localized due to the interplay between dispersion and nonlinearity. Such vortex solitons can be observed in optical media with normal dispe...
متن کاملDiscrete dark solitons with multiple holes.
We consider staggered dark solitons admitted by the discrete nonlinear Schrödinger equation with focusing cubic nonlinearity. In particular, we focus on the study of dark solitons with several holes characterized by the number of zeros in the uncoupled case. Such structures reveal interesting behaviors, such as stable intersite dark solitons. All of the structures have no counterpart in the str...
متن کاملNonlinear photonic crystals near the supercollimation point.
We uncover a strong coupling between nonlinearity and diffraction in a photonic crystal at the supercollimation point. We show that this is modeled by a nonlinear diffraction term in a nonlinear-Schrödinger-type equation in which the properties of solitons are investigated. Linear stability analysis shows solitons are stable in an existence domain that obeys the Vakhitov-Kolokolov criterium. In...
متن کاملDiscrete diffraction and spatial gap solitons in photovoltaic LiNbO3 waveguide arrays.
We investigate, experimentally and theoretically, light propagation in one-dimensional waveguide arrays exhibiting a saturable self-defocusing nonlinearity. We demonstrate low-intensity "discrete diffraction", and the high-intensity formation of spatial gap solitons arising from the first band of the transmission spectrum. The waveguide arrays are fabricated by titanium in-diffusion in a photor...
