Multi-component vector solitons in photorefractive crystals

We study the existence and stability of multi-component spatial optical solitons in anisotropic nonlocal photorefractive media. For the case of three components, we find numerically the whole family of composite solitons with two perpendicular dipole components, and show their stability for a wide range of parameters. We confirm our theoretical results by an experimental observation of these novel types of composite optical solitons in a photorefractive strontium barium niobate crystal.

Multicomponent vector solitons: theory and experiment

We study, theoretically and experimentally, multicomponent spatial solitons in nonlinear saturable (isotropic and anisotropic photorefractive) bulk media. We find numerically a family of the three-component dipole-mode solitons and demonstrate their stability in a wide range of the input parameters. We also observe the formation and stability of these spatial solitons in experiment with photorefractive strontium barium niobate (SBN) crystals.

Collisions of (2+1)D Dipole-moce Vector Solitons in an Anisotropic Nonlinear Medium

We investigate the specific influence of anisotropy on generation, stability and dynamic properties of spatial dipole-mode vector solitons in a photorefractive medium, experimentally and numerically. Further, we demonstrate collision-induced transformation of transverse to angular momentum.
