We consider reflection and transmission of polarized paraxial light beams at a plane
dielectric interface. The field transformations taking into account a finite beam width are …

We review the recent developments of spatial optical solitons in nematic liquid crystals, also
known as Nematicons. We outline their properties, linked to a reorientational nonlinearity in …

Light filaments or optical spatial solitons are self-confined (non-spreading) beams that
originate from the balance between diffraction and self-focusing in nonlinear optical media …

We study the effects caused by remote boundaries on soliton dynamics in nonlinear media
with a large range of nonlocality, and demonstrate theoretically and experimentally how …

We investigate, both experimentally and theoretically, the interaction of (2D+ 1) spatial
solitons with the boundaries of a nonlinear medium in the presence of nonlocality. We …

We investigate total internal reflection of nonlocal spatial optical solitons at the interface
between two differently oriented regions of a highly birefringent nematic liquid crystal. The …

We report experimental evidence of soliton reflection at the boundary of quadratic nonlinear
media. The evolution of beams incident upon the interface of periodically poled LiNbO_3 …

We investigate total internal reflection of optical spatial solitons at the interface between two
regions of nematic liquid crystals with different optical densities. Due to nonlinear molecular …

We experimentally demonstrate the ability of a self-guided laser beam to induce waveguides
with sharp bends. The beam is a two-dimensional photorefractive screening-photovoltaic …

Refraction of black and gray solitons at boundaries separating different defocusing Kerr
media is analyzed within a Helmholtz framework. A universal nonlinear Snell's law is …
