Beam-Splitting in plasmonic multimode waveguides based on the self-imaging effect

[摘要] A plasmonic 1 × 2 beamsplitter based on the self-imaging effect isanalysed. The simulations were performed by a 3-D full-vectorial numericalcalculation. We discuss the coupling efficiency depending on structuralparameters and on the attenuation.
