title: Analysis of the coupling of light into a metal-dielectric composite waveguide structure and its application for use as a wavelength-band selection filter.
abstract: We analyzed and experimentally tested a metal-dielectric composite waveguide structure. After coating the surface of the metal layer in the Kretschmann attenuated total internal reflection configuration with a dielectric layer, we explain the coupling of incident light into the coated layer. After finding the dispersion relationships for the layered media including the metal-dielectric composite waveguide, we can determine a solution for its existence in a complex domain. By inscribing a periodic grating structure in the dielectric layer of the metal-dielectric composite waveguide, we experimentally verify the coupling of incident light on the metal-dielectric composite waveguide structure and propose its application for use as a wavelength-band selection filter.
