Simulation of Plasmonic Microcavities — •Sven Burger, Lin Zschiedrich, Jan Pomplun, and Frank Schmidt — Zuse Institute Berlin, Berlin, Germany

Plasmon-based waveguiding structures allow for transport and storage of light at subwavelength scales. Fast and accurate 3D Maxwell solvers are needed for designing structural parameters of, e.g., hybrid plasmonic waveguides. Due to the multi-scale nature of the corresponding field distributions, accurate computation of the properties of such devices can be numerically challenging.

We have developed finite-element method (FEM) based solvers for the Maxwell eigenvalue and scattering problems. The method is based on higher order vectorial elements, adaptive unstructured grids, and on a rigorous treatment of transparent boundaries. The method has been applied to plasmonic devices like plasmonic antennas, gratings and waveguides [1-5]. Here we present 3D simulations of light propagation in plasmonic waveguides and plasmon laser cavities. We investigate the accuracy of the simulations in a convergence analysis of the numerical results.
