Minireview on Disordered Optical Metasurfaces
P. Lalanne, A. Dmitriev, C. Rockstuhl +2
The use of coherent wave phenomena to enhance device performance is a cornerstone of modern optics. In juxtaposition to (locally) periodic metasurfaces, their disordered counterpar…
Poles and zeros in non-Hermitian systems: Application to photonics
Felix Binkowski, Fridtjof Betz, Rémi Colom +2
Resonances are essential for understanding the interactions between light and matter in photonic systems. The real frequency response of the non-Hermitian systems depends on the co…
Multiple-Order Singularity Expansion Method
Isam Ben Soltane, Rémi Colom, Félice Dierick +2
Physical systems and signals are often characterized by complex functions of frequency in the harmonic-domain. The extension of such functions to the complex frequency plane has be…
Crossing of the branch cut: the topological origin of a universal 2π-phase retardation in non-Hermitian metasurfaces
Rémi Colom, Elena Mikheeva, Karim Achouri +5
Full wavefront control by photonic components requires that the spatial phase modulation on an incoming optical beam ranges from 0 to 2π. Because of their radiative coupling to the…
Enhanced Purcell factor for nanoantennas supporting interfering resonances
Rémi Colom, Felix Binkowski, Fridtjof Betz +2
We study the effect of coupled resonances and quasi-bound states in the continuum (quasi-BICs) on the Purcell factor in dielectric resonant nanoantennas. We analyze numerically int…
Modal Expansion of the Impulse Response Function for Predicting the Time Dynamics of Open Optical Cavities
Rémi Colom, Brian Stout, Nicolas Bonod
Light interaction with optical cavities is of fundamental interest to enhance the light-matter interaction and to shape the spectral features of the electromagnetic fields. Importa…
Quasinormal mode expansion of optical far-field quantities
Felix Binkowski, Fridtjof Betz, Rémi Colom +3
Quasinormal mode (QNM) expansion is a popular tool to analyze light-matter interaction in nanoresonators. However, expanding far-field quantities such as the energy flux is an open…
Gaussian regularization for resonant states: open and dispersive optical systems
Brian Stout, Remi Colom, Nicolas Bonod +1
Resonant States (RS), also known as Quasi-Normal Modes (QNMs), are eigenstates that arise in spectral expansions of linear response functions of open systems. Manipulation of these…
Modal Expansion of the Scattered Field: Causality, Non-Divergence and Non-Resonant Contribution
Rémi Colom, Ross McPhedran, Brian Stout +1
Modal analysis based on the quasi-normal modes (QNM), also called resonant states, has emerged as a promising way for modeling the resonant interaction of light with open optical c…
Polarizability Expressions for Predicting Resonances in Plasmonic and Mie Scatterers
Rémi Colom, Alexis Devilez, Stefan Enoch +2
Polarizability expressions are commonly used in optics and photonics to model the light scattering by small particles. Models based on Taylor series of the scattering coefficients…
Optimal interactions of light with magnetic and electric resonant particles
Remi Colom, Alexis Devilez, Nicolas Bonod +1
This work studies the limits of far and near-field electromagnetic response of sub-wavelength scatterers, like the unitary limit and of lossless scatterers, and the ideal absorptio…
