Abstract

We investigate the nonlinear propagation of coherent light beams in planar samples of low-birefringence nematic liquid crystals, changing the input polarization and the incidence angle in order to enhance reorientational self-focusing and generate optical spatial solitons under a variety of previously unexplored launch conditions. We find that reorientational spatial solitons require larger excitation powers in low-birefringence than in high-birefringence nematic liquid crystals but remain stable. We compare the experimental results with full-vectorial numerical simulations.
