Abstract

The interaction of twisted light beams with nematic liquid crystals is described in terms of Landau�s free energy formalism and the uniaxial dielectric model for the liquid crystal. This leads us to a partial differential equation, which is characterized by one position-dependent coefficient, governing the changes in the spatial distribution of the director orientation in the liquid crystal. Numerical solutions are determined for a typical arrangement involving a twisted nematic liquid crystal illuminated by a linearly polarized twisted light beam, predicting significant director re-orientations due to the twisted light.
