Spatial optical solitons in nematic liquid crystals are called nematicons. They occur due to the nonlinear self-focusing of an optical beam, injected laterally into a liquid crystal cell. The origin of the self-focusing can either be thermal or reorientational. In the latter case, the molecules are reoriented by the electric field of the light, which in turn changes the refractive index and causes the self-focusing. Since their first observation, the properties of these nematicons have been studied extensively in different geometries, both experimentally, theoretically and numerically. The experiments, however, are always based on the observation of the beam via scattering or by visualizing the self-induced waveguide via transverse light propagation. The observation of the beam via out-coupling has not yet been investigated for a planar geometry.
