Approach to round self-trapping in the two regimes. (squares) and (circles) vs for (a) and (b) . Horizontal lines indicate . Output intensity distribution for in the two regimes: (c) a circular soliton with a 18 μm shift and (d) an elliptical shape with a 2 μm shift. Vertical line indicates input position.

FIG. 3.

Comparison between the experimental round soliton existence points (squares) and the predicted scaling for (a) condition (i) and (b) condition (ii). The filled square refers to the observation reported in Ref. 21. The triangle refers to conditions of Fig. 1(d), leading to an elliptical beam shape.
