Intertwined Fano resonances in sub-wavelength metallic gratings: omnidirectional and wideband optical transmission
Denis Langevin, Julien Jaeck, Riad Haïdar +1
Metallic gratings can be used as infrared filters, but their performance is often limited by bandwidth restrictions due to metallic losses. In this work, we propose a metallic groo…
Electroluminescence of the graphene 2D semi-metal
A. Schmitt, L. Abou-Hamdan, M. Tharrault +18
Electroluminescence, a non-thermal radiative process, is ubiquitous in semi-conductors and insulators but fundamentally precluded in metals. We show here that this restriction can…
Experimental investigation of the thermal emission cross-section of nano-resonators using hierarchical Poisson-disk distributions
Denis Langevin, Clément Verlhac, Julien Jaeck +6
Effective cross-sections of nano-objects are fundamental properties that determine their ability to interact with light. However, measuring them for individual resonators directly…
Hybrid modes in a single thermally excited asymmetric dimer antenna
Loubnan Abou-Hamdan, Claire Li, Riad Haidar +3
The study of hybrid modes in a single dimer of neighboring antennas is an essential step to optimize the far-field electromagnetic (EM) response of large-scale metasurfaces or any…
Dark-modes excitation in coupled nano Fabry-Perot structure induced by symmetry breaking
Baptiste Fix, Julien Jaeck, Patrick Bouchon +3
Absorbing metamaterials have attracted a widespread interest but suffer from the metallic ohmic losses that limits their Q-factor to values around 10. In this paper, we report the…
Mode matching in second order susceptibility metamaterials
Sébastien Héron, Patrick Bouchon, Riad Haïdar
We present an effective model for a subwavelength periodically patterned metallic layer, its cavities being filled with a nonlinear dielectric material, which accounts for both the…
Generalized Kirchhoff law
Jean-Jacques Greffet, Patrick Bouchon, Giovanni Brucoli +2
Thermal emission can be conveniently described using Kirchhoff law which states that the emissivity is equal to the absorptivity for isothermal bodies. For a finite size system, ab…
Giant field enhancement by funneling effect into sub-wavelength slit-box resonators
Paul Chevalier, Patrick Bouchon, Riad Haidar +1
Inspired by the acoustic Helmholtz resonator, we propose a slit-box electromagnetic nanoantenna able to concentrate the energy of an incident beam into surfaces a thousand times sm…
Light funneling mechanism explained by magneto-electric interference
Fabrice Pardo, Patrick Bouchon, Riad Haïdar +1
We investigate the mechanisms involved in the funneling of the optical energy into sub-wavelength grooves etched on a metallic surface. The key phenomenon is unveiled thanks to the…
