Scattering-matrix approach for a quantitative evaluation of the topological protection in valley photonic crystals
Gaëtan Lévêque, Yan Pennec, Pascal Szriftgiser +2
In this work, we use valley-topological triangular resonators coupled to an input waveguide to evaluate the quality of the topological protection. To that purpose, we first analyze…
Vertical engineering for large stimulated Brillouin scattering in unreleased silicon-based waveguides
Laura Mercadé, Alexander V. Korovin, Yan Pennec +2
Strong acousto-optic interaction in silicon-based waveguides generally requires releasing of the silicon core to avoid mechanical leakage into the underlying silica substrate. This…
Phonon-Plasmon Interaction in Metal-Insulator-Metal Localized Surface Plasmon Systems
Abdelali Mrabti, Gaëtan Lévêque, Rana Nicolas +5
We investigate theoretically and numerically the coupling between elastic and localized surface plasmon modes in a system of gold nanocylinders separated from a thin gold film by a…
Combined photonic-plasmonic modes inside photonic crystal cavities
Abelali Mrabti, Saïd El-Jallal, Gaëtan Lévêque +3
In this article, we present a numerical study of the optical properties of a metal nanowire interacting with a localized cavity in a two dimensional photonic crystal. The nature of…
