Abstract
We present a finite element beam propagation method for the optical analysis of liquid crystal devices. In this method, the evolution of an input optical field is considered upon propagation through structures that may consist of arbitrary inhomogeneous anisotropic dielectric materials. The combination of the efficiency of the beam propagation algorithm, the flexibility of the finite element implementation and the wide applicability to general anisotropic materials makes the presented method an interesting tool for the optical analysis of photonic components. As an illustration, the diffraction of a plane wave in a structure similar to the pixels of a spatial light modulator or microdisplay is shown and the influence of the pixel dimensions is illustrated.
