A bottom-up approach towards metamaterials and plasmonics III
16:40 Invited talk : Large-area nanorod metamaterials for sensing and magneto-optics
M. Nasir, W. Dickson, G. A. Wurtz, Anatoly Zayats
King's College London (United Kingdom) We will present new approaches for large-scale, lithography-free fabrication of metamaterials based on aligned plasmonic nanorod arrays. We discuss how to achieve a designer optical properties throughout visible and near-infrared spectral ranges. The capabilities of these metamaterials in chemical sensing and for magneto-optical applications will be considered. These metamaterials open up new possibilities for a practical implementation of variety of photonic applications, including at telecommunication wavelengths.
17:00 Invited talk : THz polarization control with chiral metamaterials
M. Kafesaki, G. Kenanakis, C. M. Soukoulis, E. N. Economou
IESL-FORTH (Greece) Various bi-isotropic and bi-anisotropic chiral designs, both passive and optically controllable, are presented, and their capabilities for THz polarization control are discussed.
17:20 Invited talk : Periodic or Random Nanostructures for Light Scattering Control
Thales (France) Our paper mainly focuses on the control of light scattering by periodic or randomly rough structures. First designed with bi-periodical structures, antireflective surfaces can be achieved with random patterns. We present some new structures with periodic or random patterns, which have been designed by rigorous numerical methods (FDTD) or analytical methods. We show that random interfaces offer new degrees of freedom and possibilities by the control of their statistical properties.
17:40 Invited talk : Photonic Anderson localization in compositionally disordered two-dimensional photonic crystals
Myungjae Lee, Minsu Kang, Heonsu Jeon
Seoul National University (Korea) We employ compositionally disordered photonic crystal (PC), a photonic analogy to semiconductor alloy, as a platform to explore photonic behaviors in disordered photonic systems. A series of two-dimensional hexagonal lattice PCs are fabricated using an InGaAsP multiple-quantum-well slab, compositional disorder is introduced by randomly incorporating the air-holes of different sizes at regular lattice sites. Emission spectra and wavelength-tuned near-field scanning optical microscope images provide clear evidence that localized photonic modes can develop within the disordered structure.
