| Research Abstract |
We investigated light propagation in dye-doped nematic liquid crystals in order to form spatial optical solitons in liquid crystalline materials with high efficiency and to control their propagation. As a result, nonlinear soliton-like propagation was observed in the dye-doped liquid crystals when the polarization azimuth was orthogonal to the orientation direction of the liquid crystal. We clarified that the observed nonlinearity is due principally to the photothermal effect, which was induced by light absorption of the dye and the resultant temperature distribution in the material. In addition, we observed a light confinement effect related to the difference in refractive indices between nematic and isotropic phases.
