Plasmonic metamaterials with artificial subwavelength structures are attracting much attention. Metal nano-rods are typical plasmonic metamaterials and function as nanophotonic resonators. At the resonant conditions in the visible and near-infrared regions, the electromagnetic waves at the resonant wavelengths strongly couple with the nano-rods and are absorbed due to Joule and radiative losses. Therefore, ultrasmall wavelength-selective absorbers can be made that consist of metal nano-rods. We fabricated wavelength-selective optical attenuators, which are comprised of Au nano-rods that are integrated with silicon waveguides for optical communications. The nano-rods and silicon waveguide were fabricated on silicon-on-insulator substrates with micromachining technologies. An evanescent wave of a propagating light into the silicon waveguide was coupled with a surface-plasmon-polariton mode of the Au nano-rods at a resonant wavelength and efficiently absorbed. At a wavelength of 1565 nm, we observed optical attenuation of-17.7dB.
