A dressed polarizability framework for interface-coupled meta-atoms and large-scale metasurfaces
Peng Fu, Jean-Paul Hugonin, Maxime Bertrand +2
The modeling of large collections of interacting meta-atoms remains a central challenge in photonics because it requires the simultaneous treatment of complex scatterer geometries,…
Optical excitation of bulk plasmons in n-doped InAsSb thin films : investigating the second viscosity in electron gas
Antoine Moreau, Ãmilie Sakat, Jean-Paul Hugonin +8
We demonstrate that including the second viscosity of an electron gas in the hydrodynamic model allows for highly accurate modeling of the optical response of heavily doped semicon…
Nanometer-scale Cavities for Mid-infrared Radiation via Image Phonon Polariton Resonators
Michael Klein, Yonatan Gershuni, Alisa Perutski +2
Surface-polaritons play a pivotal role in strong light-matter interactions at the nanoscale due to their ability to confine light to deep subwavelength dimensions. A promising clas…
RETICOLO software for grating analysis
Jean Paul Hugonin, Philippe Lalanne
RETICOLO is a freeware that implements the rigorous coupled wave analysis (RCWA) for 1D (classical and conical diffraction) and 2D crossed gratings. It operates under a MATLAB envi…
Chiral TeraHertz surface plasmonics
Ian Aupiais, Romain Grasset, Dmitri Daineka +5
Chiral engineering of TeraHertz (THz) light fields and the use of the handedness of light in THz light-matter interactions promise many novel opportunities for advanced sensing and…
