Avoiding metallic walls: Use of modal superposition in plasmonic waveguides to reduce propagation loss

Optics 2013-02-26 v1

Abstract

We theoretically explore the possibility of reducing the propagation loss in a metal-insulator-metal (MIM) waveguide, using mode combinations to achieve wall-avoiding field distributions along a certain propagation length. We present analytical results for several waveguides showing notable loss reduction, and we discuss the tradeoffs between low loss and high confinement present in this technique.
