摘要： The self-focusing and the formation of spatial solitons attracted a great deal of attention since the early days of nonlinear optics. Essentially a high-power beam changes the refractive index, writing a waveguide capable to con?ne the beam itself. Accordingly, spatial solitons behave like optical waveguides for beams at different wavelength and low power, thus enabling the generation of integrated optical devices written by the light itself. Several all-optical devices have been demonstrated based on this principle, with particular attention devoted in the last two decades to nematic liquid crystals (NLCs) due to their huge nonlinear response. The main nonlinear mechanism in NLC for CW excitations is reorientational, that is, the extraordinary (e-) wave rotates the optical axis of the material, providing a focusing effect. Nonetheless, NLCs are also subject to a strong thermo-optical effect, typically yielding a defocusing effect for the e-wave. Here we demonstrate the excitation of couples of solitons with a single-humped beam caused by the interaction between reorientational and thermal nonlinearity.
