Light-trapping modes in lossy plasmonic waveguides
Source abstract
Abstract
Light-trapping modes can exist in lossless plasmonic waveguides. Here, we investigate the effect of metallic loss on light-trapping modes using the usual complex wave vector (β)-real frequency (ω) formulation and an alternative real β-complex ω formulation. It is shown that although their formation is prevented by metallic loss in the complex β-real ω formulation, light-trapping modes can exist even if there is metallic loss in the real β-complex ω formulation.
