We investigate the potential of metallic metamaterials (MM) for integrated optic applications in the
near-infrared (λ=1.5μm). Specifically we consider a composite guiding structure made of a MM layer
over a high index slab waveguide such as silicon. In this configuration only the evanescent tail
interacts with the MM layer which acts essentially as a perturbation. Our numerical simulations show
that an array of gold coupled cut wires over a slab waveguide leads to a significant variation of the slab
effective index in the vicinity of the resonance and thus can serve as building blocks for implementing
optical functions. This geometry is compatible with current nano-fabrication technologies.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
