Abstract: We present and illustrate an effective medium theory of the finite conductivity periodic finite wire medium (the bed-of-nails structure). It is constructed using a renormalization approach to...
Oral/2010: Modelling of Induced Gratings in Nonlinear Optics
Pierre Godard1, Frederic Zolla1, Andre Nicolet1
1Institut Fresnel, Aix-Marseille Université/CNRS, France
Abstract: In this paper, we present a multiharmonic model able to allow for general nonlinear optical media. As a particular example, two- and three-photon processes are...
Oral/2011: Analysis of diffraction gratings via their resonances
Benjamin Vial1,2, Mireille Commandre1, Frederic Zolla1, Andre Nicolet1, Stephane Tisserand2
1Institut Fresnel UMR CNRS 6133, Aix-Marseille Université, Ecole Centrale de Marseille
2Silios Technologies, France
Abstract: We analyze diffraction gratings via their resonances by a direct determination of the eigenmodes and the complex eigenfrequencies using a finite element method (FEM), that...
Oral/2012: Transformation Optics PML and quasi-mode analysis: application to diffraction gratings
Benjamin Vial1,2, André Nicolet1, Frédéric Zolla1, Guillaume Demésy1, Mireille Commandré1, Stéphane Tisserand2
1aInstitut Fresnel UMR CNRS 6133, Aix-Marseille Universite, France
2Silios Technologies, France
Abstract: This paper presents the Perfectly Matched Layers (PMLs) in the framework of transformation optics as a complex valued change of coordinates. PMLs provide the suitable operator...
Poster/2012: 1D model for low power soliton hybridized with a plasmon in realistic nonlinear planar structures
Wiktor Walasik1, Yaroslav Kartashov2, André Nicolet1, Gilles Renversez1
1Aix-Marseille Université, CNRS, Institut Fresnel UMR 7249, France
2Institute of Spectroscopy, Russian Academy of Sciences, Troitsk, Russia
Abstract: We study the propagation of nonlinear waves in layered nonlinear dielectric/linear dielectric/metal planar structures. We generalyze a 1D vector model that describes the light propagation in such...
