Asymmetric spatial profiles and multivalued features are predicted for self-localized light versus walk-off angle. The results hold valid for generic self-focusing birefringent media and apply to large angle steering of individual and multiple self-trapped optical beams.4 pages, 4 figuresOpticsSoft Condensed MatterPattern Formation and Solitonstext
