Optical spatial solitons have been demonstrated in bulk nematic liquid crystals. We present an overview of our recent experimental results on nonlinear wave propagation in nematic liquid crystals, focusing on spatial solitons through the reorientational nonlinear response. Various phenomena, including spatial readdressing, weak signal guiding and two-soliton interactions, are observed in voltage biased planar cells.

Basing on Landau–de Gennes theory, this study investigated the chiral configurations of nematic liquid crystals confined to cylindrical capillaries with homeotropic anchoring on the cylinder walls. When the elastic anisotropy (L2/L1) is large enough, a new structure results from the convergence of two opposite escape directions of the heterochiral twist and escape radial (TER) configurations. The new defect presents when L2/L1≥7 and disappears when L2/L1<7. The new structure possesses a heterochiral hyperbolic defect at the center and two homochiral radial defects on both sides. The two radial defects show different chiralities.
