A bottom-up approach towards metamaterials and plasmonics II

14:00 Invited talk : Linear and Nonlinear Plasmonics

Augustine Urbas

Air Force Research Lab (USA)

Fundamental challenges in understanding and implementation still loom in the arena of materials for nanoscale optics and plasmonics. Furthermore, significant limitations for application in nonlinear optics are present in noble metal plasmonic structures due to their stability under optical and thermal load and their properties in other, equally interesting and potentially more useful, spectral regions. In this presentation we develop a connection between the properties of plasmonic materials and opportunities for their use in challenging environments.

We demonstrate the bottom-up engineering of active semiconductor/rare earth-ion nano-hybrids and switchable polaritonic/plasmonic nano-bismuth structures. We show that these non-conventional nanoscale elements can be assembled into multiscale optical metamaterial architectures for integrated nanophotonic solutions with lighting, light modulation and ultra-sensitive environmental sensing functionalities.

Metallodielectric composites are very interesting from the point of view of metamaterials and plasmonics. For the fabrication of self-organized metallodielectric micro/nanostructures, one particularly promising approach is based on the directional solidification of eutectics. Here we demonstrate a bulk three-dimensional nanoplasmonic eutectic composite which was obtained by bottom-up approach. This material exhibits localized surface plasmon resonance (LSPR) at visible wavelengths.

15:00 Invited talk : Synthesis and Applications of Confined Plasmonic Nanoparticles in Hollow Structures

Miguel A. Correa-Duarte

Universidade de Vigo (Spain)

The synthetic architectures of complex nanostructures, including multifunctional hollow capsules, are expected to play key roles in many different applications, such as drug delivery, photonic crystals, nanoreactors, and sensing. Implementation of novel strategies for the fabrication of such materials is needed because of the infancy of this knowledge, which still limits progress in certain areas.

15:20 Invited talk : Microfluidic synthesis of acoustic silica microresonators: evidence for a metamaterial with negative refractive index

Simon Raffy, Benoit Mascaro, Thomas Brunet, Jacques Leng, Olivier Mondain-Monval

University of Bordeaux (France)

Using a microfluidic device, we synthesized monodisperse porous silica particles, which act as microresonators when dispersed in a gel phase. The final dispersion presents a broad frequency range over which the phase velocity and the refractive index are negative.

Here, I will present a versatile platform technology that, based on resonant optical antenna structures, allows for an efficient coupling of incoming light into propagating graphene plasmons. More importantly, I will show that these antennas and the use of spatial conductivity patterns (e.g. double layer graphene patches) also allow for controlling the graphene plasmons wavefronts, constituting an essential step for the development of graphene plasmonic circuits.
