Abstract

This work presents an experimental and theoretical analysis of beam propagation in multiple layers formed by chiral nematic liquid crystal. Depending on structure parameters light can be guided in a single layer or propagate in a matrix of coupled layers in a discrete way. It is also shown that the nonlinear behavior leads to creation of spatial solitons (nematicons) in both discrete and single-layer configurations.
