Dielectric-loaded surface plasmon−polariton waveguides (DLSPPWs) are a practically
valuable type of plasmonic waveguide. The properties of DLSPPWs at telecommunication
wavelengths have been studied in detail. However, the efficient optical excitation of DLSPPWs
in the visible spectral range has still not been realized. In this work, we present the results of
our experimental investigations of DLSPPWs in the visible spectral range. In addition, a new
configuration for the excitation and detection of the DLSPPW mode has been proposed and
realized. The propagation of the DLSPPW plasmon mode up to a distance of 45 μm has been
demonstrated.
