Nematicons properties and stability in chiral nematic liquid crystal

摘要

We report on the experimental and numerical results of the nonlinear light beam propagation in planar samples of chiral nematic liquid crystals, for both high- and low-birefringence chiral nematic liquid crystals. We investigate the properties and stability of obtained nematicons. We found that reorientational spatial solitons require larger excitation powers in low-birefringence chiral nematics than in high-birefringence but remain more stable and self-focused.
