Discrete Light Propagation and Self-Localization in Voltage-Controlled Arrays of Channel Waveguides in Undoped Nematic Liquid Crystals

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. The predictions, based on full numerical BPM simulations, are in excellent agreement with the experimental results.

Discrete light propagation and self-trapping in liquid crystals

We investigate light propagation and self-localization in a voltage-controlled array of channel waveguides realized in undoped nematic liquid crystals. We report on discrete diffraction and solitons, as well as all-optical angular steering and the formation of multiband vector breathers. The results and are in excellent agreement with both coupled mode theory and full numerical simulations.

Optical multiband vector breathers in tunable waveguide arrays

We investigate multiband optical breathers in a voltage-adjustable array of coupled waveguides in nematic liquid crystals. Symmetric breathers resulting from vector composition of modes from two bands are observed over large propagation distances and are described in terms of the Floquet-Bloch theory.
