Design and optimization of an AZO-based plasmonic metasurface-driven optical solar reflector for thermal management
Lucas Viseur, Alexandre Mayer, Luc Henrard +1
Plasmonic metasurface-driven Optical Solar Reflectors (m-OSRs) offer a promising route towards lightweight and high-performance thermal management. By exploiting subwavelength stru…
All-optical programming of polarization singularities in a photonic-crystal laser
Abhishek Padhy, Zhiyi Yuan, Mohammed Hamdad +11
Singular optics has emerged as an important research area with diverse applications, yet controlling optical singularities in nanophotonic emitters remains largely constrained by t…
Towards Photonic Band Diagram Generation with Transformer-Latent Diffusion Models
Valentin Delchevalerie, Nicolas Roy, Arnaud Bougaham +3
Photonic crystals enable fine control over light propagation at the nanoscale, and thus play a central role in the development of photonic and quantum technologies. Photonic band d…
Twist-Induced Beam Steering and Blazing Effects in Photonic Crystal Devices
Nicolas Roy, Beicheng Lou, Shanhui Fan +2
Twisted bilayer photonic crystals introduce a twist between two stacked photonic crystal slabs, enabling strong modulation of their electromagnetic properties. The change in the tw…
Photonic Structures Optimization Using Highly Data-Efficient Deep Learning: Application To Nanofin And Annular Groove Phase Masks
Nicolas Roy, Lorenzo König, Olivier Absil +3
Metasurfaces offer a flexible framework for the manipulation of light properties in the realm of thin film optics. Specifically, the polarization of light can be effectively contro…
New horizons in near-zero refractive index photonics and hyperbolic metamaterials
Michaël Lobet, Nathaniel Kinsey, Iñigo Liberal +7
The engineering of the spatial and temporal properties of both the electric permittivity and the refractive index of materials is at the core of photonics. When vanishing to zero,…
A tutorial on the conservation of momentum in photonic time-varying media
Angel Ortega-Gomez, Michaël Lobet, J. Enrique Vázquez-Lozano +1
Time-varying media break temporal symmetries while preserving spatial symmetries intact. Thus, it represents an excellent conceptual framework to investigate the fundamental implic…
Momentum considerations inside near-zero index materials
Michaël Lobet, Iñigo Liberal, Larissa Vertchenko +3
Near-zero-index (NZI) materials, i.e. materials having a phase refractive index close to zero, are known to enhance or inhibit light-matter interactions. Most theoretical derivatio…
Electrodynamic models of 2D materials: can we match thin film and single sheet approaches?
Bruno Majérus, Evdokia Dremetsika, Michaël Lobet +2
The electromagnetic properties of 2D materials are modeled either as single sheets with a surface susceptibility or conductivity, or as thin films of finite thickness with an effec…
Probing graphene χ(2) using a gold photon sieve
Michael Lobet, Michael Sarrazin, Francesca Cecchet +4
Nonlinear second harmonic optical activity of graphene covering a gold photon sieve was determined for different polarizations. The photon sieve consists of a subwavelength gold na…
Plasmon hybridization in pyramidal metamaterials: a route towards ultra-broadband absorption
Michael Lobet, Mercy Lard, Michael Sarrazin +2
Pyramidal metamaterials are currently developed for ultra-broadband absorbers. They consist of periodic arrays of alternating metal/dielectric layers forming truncated square-based…
Carpet cloaking on a dielectric half-space
Pu Zhang, Michaël Lobet, Sailing He
Carpet cloaking is proposed to hide an object on a dielectric half-space from electromagnetic (EM) detection. A two-dimensional conformal transformation specified by an analytic fu…
