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…
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…
