Enhanced selfphase modulation in silicon nitride waveguides with integrated 2D MoS2 films
Shahaz S. Hameed, Di Jin, Aihao Zhao +9
On-chip integration of 2D materials provides a promising route towards next-generation integrated optical devices with performance beyond existing limits. Here, significantly enhan…
A formalism for giant Goos-Hänchen shift in metasurface sensors with phase singularity
Lotfi Berguiga, Sébastien Cueff, Lydie Ferrier +4
The Goos-Hänchen (GH) shift becomes giant in resonant photonic structures, making it promising for refractive index sensors with ultimate sensitivities. We provide here a complete…
Spatially-Controlled Planar Guided Crystallization of Low-Loss Phase Change Materials for Programmable Photonics
Fouad Bentata, Arnaud Taute, Capucine Laprais +14
Photonic integrated devices are progressively evolving beyond passive components into fully programmable systems, notably driven by the progress in chalcogenide phase-change materi…
Strong and Engineerable Optical Anisotropy in Easily Integrable Epitaxial SrO(SrTiO 3 ) N Ruddlesden--Popper Thin Layers
Mohamed Oussama Bounab, Clarisse Furgeaud, Sébastien Cueff +7
Optical anisotropy is a key property for numerous photonic devices. However, bulk anisotropic materials suitable for such applications remain relatively scarse and are often challe…
Tailoring Flatband Dispersion in Bilayer Moiré Photonic Crystals
Chirine Saadi, Sébastien Cueff, Lydie Ferrier +6
In this study, we experimentally investigate the photonic dispersion in one-dimensional moiré structures formed by stacking two photonic crystal slabs with slightly different peri…
