Abstract

Laser beam propagation through and absorption in composite and anisotropic media is simulated by solving numerically Maxwell’s equations with the FDTD method. Laser treatment of materials, light beam transformation in micron-sized optical fiber systems and liquid crystalline materials, generation of optical vortices (beams with non-zero orbital angular momentum) due to interaction with liquid crystal disclinations are considered. Typical grids used for simulations consist of tens and hundreds of millions of cells. The numerical code is parallelized using geometrical domain decomposition and the MPI library for data transfer between nodes of a computational cluster.
