In this report, the results of numerical simulations describing (discrete) light propagation in photonic liquid crystal fibers (PLCFs) are presented. Specifically, the deviation in the spatial broadening of the beams characterized by different initial widths is analyzed. In this context, particular attention is devoted to the cases in which thermal (optical) nonlinearity in liquid crystals (LCs) is taken into account. Spatial light localization and/or delocalization are demonstrated, with the final scenario determined by the initial width and amplitude of the light beam. In particular, possibility of the discrete soliton generation is demonstrated. A qualitative comparison with experimental data obtained in analogous conditions (with use of specific PLCF samples) is also made.
