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…
SO(2) and O(2) Equivariance in Image Recognition with Bessel-Convolutional Neural Networks
Valentin Delchevalerie, Alexandre Mayer, Adrien Bibal +1
For many years, it has been shown how much exploiting equivariances can be beneficial when solving image analysis tasks. For example, the superiority of convolutional neural networ…
