Discontinuities in open photonic waveguides: Rigorous 3D modeling with the finite element method
Guillaume Demésy, Gilles Renversez
In this paper, a general methodology to study rigorously discontinuities in open waveguides is presented. It relies on a full vector description given by Maxwell's equations in the…

Electromagnetic waves in photonic crystals: laws of dispersion, causality and analytical properties
Boris Gralak, Maxence Cassier, Guillaume Demésy +1
Photonic crystals are periodic structures which prevent light propagation along one or more directions in certain frequency intervals. Their band spectrum is usually analyzed using…

Non-linear eigenvalue problems with GetDP and SLEPc: Eigenmode computations of frequency-dispersive photonic open structures
Guillaume Demésy, André Nicolet, Boris Gralak +3
We present a framework to solve non-linear eigenvalue problems suitable for a Finite Element discretization. The implementation is based on the open-source finite element software…
