Surface plasmon polaritons in metal-semiconductor hybrid structures — •Patrick Scholz, Stephan Schwieger, David Leipold, and Erich Runge — Technische Universität Ilmenau, Institut für Physik, 98693 Ilmenau

We present Finite Difference Time Domation (FDTD) and finite element simulations of nanostructured metal-semiconductor hybrid structures illuminated by visible and near IR light. Such structures will be important for novel optical devices, as they allow to confine the electromagnetic field in subwavelength dimensions and control the life time and the dispersion of the optical excitations. The considered systems consist of nanostructured metal layers (e.g. an array of nanometer-sized metal wires) embedded in a multilayer system that contains different semiconductor layers. We discuss the influence of the geometry of the semiconductor layers on surface plasmon polaritons excited at the metal nanostructures.
