2020High Quality Factor Confinement Of Bloch Surface Waves At Visible Wavelengths
Hans Peter Herzig, Gaël David Osowiecki, Nicolas Maxime André Descharmes, Babak Vosoughi Lahijani, Raphaël Barbey
We report the first experimental demonstration of high quality factor confinement of Bloch surface waves at visible wavelengths. The cavities consist of planar Fabry-Perot resonators that are fabricated on top of a Bloch surface supporting substrate. This ...
IEEE2018Postpolymerization Modification of Poly(glycidyl methacrylate) Brushes: An XPS Depth-Profiling Study
Harm-Anton Klok, Vincent Laporte, Raphaël Barbey
Surface-initiated polymerization represents a versatile strategy to modify a diverse range of materials with thin, functional polymer coatings. While in many cases the desired functional groups can be directly incorporated via (co)polymerization of the app ...
