Abstract
We show that light-induced modification of the anchoring conditions can lead to an extraordinarily large optical response in dye-doped nematic liquid crystals. The bulk reorientation due to the collective elastic behavior of the liquid crystal is the origin of the nonlinearity, which occurs without a direct optical torque on the molecular director in the bulk, We call this effect SINE (Surface Induced Nonlinear Effect). These results can also explain the origin of the supra-nonlinear behavior recently observed in the same composites.
