    Abstract

    We investigate light self-confinement in nematic liquid crystals with homogeneous planar distribution of the molecular director. Using comb-patterned electrodes we are able to vary the initial orientation, exploiting different degrees of nonlinearity by the electro-optic effect. We experimentally demonstrate tuning of the nonlinearity by studying both single nematicon propagation and planar interactions between two nematicons.
