We review linear and nonlinear light propagation in a voltage-tunable liquid crystalline waveguide array. We report on discrete diffraction, discrete soliton generation, all-optical beam steering, multiband vector breathers and Bloch oscillations. Th

In this paper the tunable properties of the photonic liquid crystal fibers are analyzed. Both numerical and experimental results on the linear light propagation in the photonic crystal fiber filled with the glycerin-water solution and with 6CHBT nema

In this paper we present numerical and experimental results of propagation and polarization properties of the photonic liquid crystal fibers (PLCFs) in which only selected micro holes were filled with nematic liquid crystal (LC) guest materials. As a

We investigate linear and nonlinear light propagation in the photonic crystal fibers infiltrated with nematic liquid crystals. Such a photonic structure, with periodic modulation of refractive index, which could be additionally controlled by the temp

In our work we investigate the hexagonal matrix of cylindrical step-index waveguides placed inside a silica fiber. The linear and nonlinear parameters of the analyzed structure are optimized to observe discrete diffraction and creation of discrete sp

In this work we investigate light beam propagation in twisted nematic liquid crystalline film. In the linear case (for low power of the light beam) the diffraction and walk-off of the light beam is observed. Due to the optical reorientation nonlinear
