Hyperbolic metamaterials comprised of an array of plasmonic nanorods provide a unique platform for designing optical sensors and integrating nonlinear and active nanopho-tonic functionalities. In this work, the waveguiding properties and mode structure of planar anisotropic metamaterial waveg-uides are characterized experimentally and theoretically. While(More)
Nonlinear optical materials comprise the foundation of modern photonics, offering functionalities ranging from ultrafast lasers to optical switching, harmonic and soliton generation. Optical nonlinearities are typically strong near the electronic resonances of a material and thus provide limited tuneability for practical use. Here we show that in plasmonic(More)
This paper describes the formation of mono-domain highly ordered nanoporous alumina on the scale of a 2 inch diameter silicon wafer by anodization of aluminium evaporated on a patterned SiO(2) mask on a silicon substrate. The position of the ordered pores correlates with holes in the SiO(2) mask, which guide the electric field during anodization and(More)
