Simulations of Liquid Crystal Infiltrated Photonic Crystal Fibers Using the Fourier Modal Method — •Thomas Zebrowski, Sabine Essig, and Kurt Busch — Institut für Theoretische Festkörperphysik and DFG-Center for Functional Nanostructures (CFN), Karlsruher Institut für Technologie (KIT), 76128 Karlsruhe, Germany

Liquid crystal infiltrated photonic crystal fibers are challenging systems for an accurate simulation because of their characteristic tiny features in the transverse plane coupled with a huge aspect ratio in propagation direction. In this contribution we demonstrate that the Fourier Modal Method is applicable to treat such problems. First, we extend the method to handle anisotropic materials and fully exploit the system symmetries which leads to significantly reduced demand for computational resources. This allows to make maximum use of the method's advantages which come via a scattering matrix algorithm that handles the typically slow or periodic structural variations along the propagation direction.
