Journal ArticleDOI
Quasimodal expansion of electromagnetic fields in open two-dimensional structures
TL;DR: A quasimodal expansion method (QMEM) was developed in this article to model and understand the scattering properties of arbitrary shaped two-dimensional open structures, where the transformed operator at stake is no longer self-adjoint, and classical modal expansion fails.
Journal ArticleDOI
Wafer Scale Formation of Monocrystalline Silicon-Based Mie Resonators via Silicon-on-Insulator Dewetting
Marco Abbarchi,Meher Naffouti,Meher Naffouti,Benjamin Vial,Abdelmalek Benkouider,Laurent Lermusiaux,Luc Favre,Antoine Ronda,Sébastien Bidault,Isabelle Berbezier,Nicolas Bonod +10 more
TL;DR: The capabilities of a dewetting-based process, independent of the sample size, to fabricate Si-based resonators over large scales starting from commercial silicon-on-insulator (SOI) substrates are reported.

TL;DR: In this article, numerical methods for modeling light diffraction by periodic structures having one-, two-, or three-dimensional periodicity are presented. And each of these models has a specific theoretical method aiming to a direct numerical application by university and industrial researchers.
Journal ArticleDOI
Topology optimized all-dielectric cloak: design, performances and modal picture of the invisibility effect.
Benjamin Vial,Yang Hao +1 more
TL;DR: A gradient based topology optimization is employed to find a dielectric permittivity distribution that minimizes the diffracted field in free space and a modal analysis is carried out providing physical insights on the resonant cloaking mechanism at stake.
Journal ArticleDOI
A coupling model for quasi-normal modes of photonic resonators
Benjamin Vial,Yang Hao +1 more
TL;DR: In this paper, the authors developed a model for the coupling of quasi-normal modes in open photonic systems consisting of two resonators, where the modes of the coupled system were expressed as a linear combination of the individual particles, and a generalized eigenvalue problem involving small size dense matrices.
