Non-uniqueness of the Quasinormal Mode Expansion of Electromagnetic Lorentz Dispersive Materials
Alexandre Gras, Philippe Lalanne, Marc Duruflé
Any optical structure possesses resonance modes and its response to an excitation can be decomposed onto the quasinormal and numerical modes of discretized Maxwell's operator. In t…

Quasinormal-mode analysis of grating spectra at fixed incidence angles
Alexandre Gras, Wei Yan, Philippe Lalanne
Grating spectra exhibit sharp variations of the scattered light, known as grating anomalies. The latter are due to resonances that have fascinated specialists of optics and physics…

Quasinormal mode solvers for resonators with dispersive materials
P. Lalanne, W. Yan, A. Gras +16
Optical resonators are widely used in modern photonics. Their spectral response and temporal dynamics are fundamentally driven by their natural resonances, the so-called quasinorma…
