Abstract

Using modulation theory, we develop a simple ((2+1) dimensional) model to describe the synergy between the thermo-optical and reorientational responses of nematic liquid crystals to light beams in order to describe the routing of spatial optical solitary waves— nematicons— in such a uniaxial environment. Introducing several approximations based on the nonlocal physics of the material, we are able to predict the trajectories of nematicons and their angular steering with temperature, accounting for the energy exchange between the input beam and the medium through one photon absorption. The theoretical results are then compared with experimental data from previous studies, showing excellent agreement.
