We investigate, both theoretically and experimentally, selftrapping of light beams in nematic liquid crystals arranged so as to exhibit the optical Freedericksz transition in planar cells. The resulting threshold in the nonlinear reorientational response supports a bistable behavior between diffracting and self-localized beam states, leading to the appearance of a hysteretic loop versus input excitation. Our results confirm the role of nematic liquid crystals in the study of non-perturbative nonlinear photonics. (C) 2014 Optical Society of America
