Recent Advances in Resonant Waveguide Gratings

Olivier Martin, Benjamin Gallinet, Giorgio Quaranta, Guillaume Basset

Resonant waveguide gratings (RWGs), also known as guided mode resonant (GMR) gratings or waveguide-mode resonant gratings, are dielectric structures where these resonant diffractive elements benefit from lateral leaky guided modes from UV to microwave freq ...

Light refocusing with up-scalable resonant waveguide gratings in confocal prolate spheroid arrangements

Olivier Martin, Benjamin Gallinet, Zdenek Benes, Giorgio Quaranta, Guillaume Basset

Resonant waveguide gratings (RWGs) are thin-film structures, where coupled modesinterfere with the diffracted incoming wave and produce strong angular and spectral filtering. The combination of two finite-length and impedance matched RWGs allows the creati ...

Color-Selective and Versatile Light Steering with up-Scalable Subwavelength Planar Optics

Olivier Martin, Giorgio Quaranta, Benjamin Gallinet, Guillaume Basset

Resonant waveguide gratings (RWGs) are subwavelength structures of great interest for biosensors, optical filters and optical security applications. We demonstrate and characterize a beam steering device, where the in-coupling and out-coupling processes ma ...

Resonant absorption of a chemically sensitive layer based on waveguide gratings

Hans Peter Herzig, Vincent Paeder, Laurent Davoine, Marc Schnieper, Guillaume Basset

A colorimetric sensor providing a direct visual indication of chemical contamination was developed. The sensor is a combination of a chemically sensitive dye layer and a resonant waveguide grating. Enhancement of the light absorption by the photonic struct ...
