“…This means that for sufficiently small values of ν it is completely justified to neglect the nonlocality in longitudinal direction. Notice also that this assumption was used in a number of previous experimental investigations where an excellent agreement between experimental observations and theoretical predictions was found [17,18,23]. We thus concentrate on the model (2).…”

We address the stabilization of dipole solitons in nonlocal nonlinear materials by two different approaches. First, we study the properties of such solitons in thermal nonlinear media, where the refractive index landscapes induced by laser beams strongly depend on the boundary conditions and on the sample geometry. We show how the sample geometry impacts the stability of higherorder solitons in thermal nonlinear media and reveal that dipole solitons can be made dynamically stable in rectangular geometries in contrast to their counterparts in thermal samples with square cross-section. Second, we discuss the impact of the saturation of the nonlocal nonlinear response on the properties of multipole solitons. We find that the saturable response also stabilizes dipole solitons even in symmetric geometries, provided that the input power exceeds a critical value.

“…Nonlocal spatial solitons are extensively investigated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] since the pioneering work of Snyder and Mithchell [1]. A topic that has captured a rising interest is the interaction between solitons and the boundaries [4][5][6][7][8], especially in lead glass.…”

Boundary force exerted on spatial solitons in cylindrical strongly nonlocal media

et al. 2009

We investigate the propagation of the spatial soliton in cylindrical strongly nonlocal media by a novel method of image beam of light. The effect of the boundary on the soliton acting as the dynamic force for the soliton steering is equivalent to the force between the soliton beam and the image beam. The trajectory of the soliton is analytically studied which is in good agreement with the experimental results.

“…In the literature, interaction with boundaries was studied earlier than in [24], e.g., in lead glasses [25][26][27][28][29] and in NLC [30,31]. The VA itself was applied to nematicons in a biased cell well before Petrovic et al, see [32,33].…”
