Sources as an Extension of the Fourier Modal Method — •Christian Klock1, Thomas Zebrowski1,2,3, Sabine Essig1,2,3, and Kurt Busch1,2,3 — 1Institut für Theoretische Festkörperphysik, Universität Karlsruhe — 2Karlsruhe School of Optics & Photonics (KSOP) — 3DFG Center for Functional Nanostructures (CFN)
The Fourier Modal Method (FMM) enables the study of electromagnetic field distribution in structures with periodicity in the lateral plane. A nonlinear conformal coordinate mapping realizes absorbing boundaries and also allows us to treat aperiodic, finite-sized structures. Commonly, the method is used to simulate a system’s response to an incoming wave.
Our poster illustrates how to extend the method to include the emission from line sources in 2D and point sources in 3D. We present comparisons of numerical and analytical field distributions for the case of an emitter in an infinite dielectric cylinder. Furthermore, we demonstrate the method’s potential for applications related to the designs of structured, plasmonic enhanced light emitting diodes.
