TaCoNa-Photonics 2009Optical properties of a metallic meander Fabry-Perot cavityLiwei Fu1, Heinz Schweizer1,2, Thomas Weiss1, Harald Giessen114th Physics institute, University of Stuttgart, Pfaffenwaldring 57, 70550 Stuttgart, Germany 2LASMEA, Universite Blaise Pascal, F-63177 Aubiere Cedex, France Abstract: A single layer metallic meander structure is favorable to support surface plasmon polaritons. We combine two single meander layers to form a Fabry-Perot cavity and investigate its optical properties. In a proper distance, the cavity behaves as a single layer meander, in which enhanced transmission and negative mode dispersion are present. In contrast to the single layer, however, the surface waves from the two mirrors are still coupled together resulting in an amplified longitudinal E-field propagating backwards inside the cavity. The backward wave can be observed at visible frequencies with low loss high transmittance for structural parameters that are well suited for nano-fabrication. Such a compact realization of negative refraction is a promising approach for future applications. Presentation type: Poster |
