Abstract
We demonstrate, theoretically and experimentally, that dipole-mode vector solitons created in biased photorefractive media possess a number of anisotropy-driven properties, such as stability of a selected orientation, wobbling, and incomplete rotation, owing to the anisotropic nonlocal response of the photorefractive nonlinearity. Such features are found for higher-order (multipole) vector solitons, and they are carefully verified in an experiment.
