Metamaterials promise the possibility to tailor the propagation properties of light at the nano-scale. With this contribution we explore the possibility to combine the concept of metamaterials with integrated optics. We investigate a system consisting of a one-dimensional array of double cut-wires (two very thin gold sheets separated by a dielectric spacer) placed on top of a dielectric slab waveguide, which supports only the fundamental TE and TM mode in the near infrared spectral region around 1550 nm. Strong coupling of the waveguide modes to the plasmonic eigenmodes of the double cut-wire is achieved via the longitudinal component of the electric field, being relatively large for an asymmetric refractive index profile. By tuning the length of the double cutwires, we can tune the spectral position of the occurring hybrid resonance. We will show by rigorous calculations, that the resonance is anti-symmetric and hence produces artificial magnetism at optical frequencies in this simple scheme. To further explore the physics of the system, we investigate the dispersion relation of a periodic array of double cut-wires with varying lattice periods. The slab waveguide mode leads to a coupling of the individual plasmonic nanostructures. We find that for short lattice periods the dispersion closely resembles that of the slab waveguide. However when the Bragg frequency approaches the plasmonic resonance frequency, a strong interaction takes place and leads to a back-bending of the dispersion relation with regions of negative group velocity near to the band edge while an avoided crossing of both resonances takes place.
