Abstract

Dispersion characteristics of rotated wavelength-scaled dielectric-metal interfacial gratings with two different multilayer compositions corresponding to the same modulation amplitude was investigated. It was shown that double reflectance minima appear inside a finite spectral region in between two different azimuthal orientations: at 0° azimuthal angle (P-orientation) and at ∼30° azimuthal angle (C-orientation). The modes propagating in the valleys are short-range in P-orientation, while the coupled modes confined at valley-edges exhibit long-range SPP features in C-orientation. Their E-field distribution and large propagation length is promising in bio-sensing applications.
