Exploring phase sensitivity and limit of detection near the critical coupling of metasurfaces and its phase singularity
L. Berguiga, T. Girerd, X. Letartre +4
It is commonly accepted that phase singularities in refractive index sensors can provide highly sensitive detection. To address this issue, we studied the phase sensitivity and the…
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…
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…
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…
