Guided wave metamaterial configurations for application in the near IR domain

We address the potential of a metamaterials in a guided wave configuration for applications in the near IR domain. We consider a hybrid type structure made of 2D metamaterial array over a high index slab waveguide, as for instance silicon our case. The experimental and modeling results show that effective index and loss level in such hybrid waveguides can be carefully controlled by the engineering of metamaterial resonances. The investigated approach may constitute a promising alternative to the bulk multi-layers metamaterial structures.
