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…
