We demonstrate that optical spatial solitons with non-rectilinear trajectories can be made to propagate in a uniaxial dielectric with a transversely modulated orientation of the optic axis. Exploiting the reorientational nonlinearity of nematic liqui

While curved waveguides are fundamental elements in photonics, those induced all-optically in nonlinear uniform dielectrics tend to be straight. In uniaxial soft matter with a reorientational response, such as nematic liquid crystals, light beams in

In this study, a variable capacitor made of a nematic liquid crystal cell is proposed and analyzed theoretically. The mutual capacitance is steered with an optical beam of a Gaussian shape launched into the cell. The optical field changes the orienta

Design of a false color palette is quite easy but some more effort is required to achieve a good dynamic range, contrast and overall appearance of the palette. Such palettes, for instance, are commonly used in scientific papers for data presentation.

In the following paper we present numerical results of light propagation in a cell filled with low birefringent chiral nematic liquid crystals with a small pitch. Due to the periodicity of a structure typical diffraction is substituted with the discr

By lunching the beam into the chiral nematic liquid crystals it is possible to achieve a non-diffractive beam similar to a soliton. This effect is caused by the molecular reorientation i.e. nonlinear response of the material forming the areas of high

In this paper, the theoretical analyses of optically induced molecular reorientation are presented in a nematic liquid crystal cell. Due to the absorption of the light beam, the temperature of the cell increases, which induces change of anisotropy an

We investigate nonlinear self-focusing and nematicon generation in low birefringencenematic liquid crystals (NLCs), where n=0.04. Nematicons are obtained for larger optical powers but they are more than in NLCs with standard birefringence, of the ord
