Controlled propagation and structural transformation of the beam in complex potential wells

The formation of optical solitons in nonlinear media is governed by the balance among diffraction effects, potential well confinement, and nonlinear effect interactions, a dynamic process that is critically determined by the configuration of the potential well. The results demonstrate that adjusting the spatial arrangement of the potential well enables precise control over the structural shaping of the optical beam. The introduction of a rotational structure within the potential well can induce rotational dynamics in the optical field. The gradual change potential well structure supports the stable morphological transformation of solitons, accommodating isotropic and anisotropic modulation. These findings provide a theoretical foundation for potential applications in advanced optical technologies, such as beam shaping and optical signal processing.
