Narrowband Optical Coupler Using Fano Interference in First Order Diffraction
Olivier Martin, Benjamin Gallinet, Giorgio Quaranta, Fabian Michael Lütolf
Light coupling in waveguides has been extensively investigated in a variety of contexts, from photonic integrated circuits to biosensing and near-eye displays for augmented reality. Here, narrowband diffraction is reported using a Fano interference effect ...
AMER CHEMICAL SOC2021Light refocusing with up-scalable resonant waveguide gratings in confocal prolate spheroid arrangements
Olivier Martin, Zdenek Benes, Benjamin Gallinet, 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 ...
2018Recent 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 ...
2018Color-Selective and Versatile Light Steering with up-Scalable Subwavelength Planar Optics
Olivier Martin, Benjamin Gallinet, Giorgio Quaranta, 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 ...
2017Fano-resonant aluminum and gold nanostructures created with a tunable, up-scalable process
Olivier Martin, Benjamin Gallinet
An up-scalable approach for creating Fano-resonant nanostructures on large surfaces at visible wavelengths is demonstrated. The use of processes suitable for high throughput fabrication and the choice of aluminum as a cost-efficient plasmonic material ensu ...
Royal Society of Chemistry2015Numerical methods for nanophotonics: standard problems and future challenges
Olivier Martin, Jérémy Butet, Benjamin Gallinet
Nanoscale photonic systems involve a broad variety of light-matter interaction regimes beyond the diffraction limit and have opened the path for a variety of application opportunities in sensing, solid-state lighting, light harvesting, and optical signal p ...
Wiley-VCH Verlag Berlin2015Nanostructure Symmetry: Relevance for Physics and Computing
Marc-André Dupertuis, Daniel Oberli, Benjamin Gallinet, Sascha Dalessi
We review the research done in recent years in our group on the effects of nanostructure symmetry, and outline its relevance both for nanostructure physics and for computations of their electronic and optical properties. The exemples of C3v and C2v quantum ...
Amer Inst Physics2014Mechanisms of Fano Resonances in Coupled Plasmonic Systems
Olivier Martin, Andrea Lovera, Benjamin Gallinet
Fano resonances in hybridized systems formed from the interaction of bright modes only are reported. Despite precedent works, we demonstrate theoretically and experimentally that Fano resonances can be obtained by destructive interference between two brigh ...
Amer Chemical Soc2013Plasmonic Radiance: Probing Structure at the Ångström Scale with Visible Light
Olivier Martin, Benjamin Gallinet, Thomas Gerd Siegfried
Plasmonic modes with long radiative lifetimes combine strong nanoscale light confinement with a narrow spectral line width carrying the signature of Fano resonances, making them very promising for nanophotonic applications such as sensing, lasing, and swit ...
2013Second-harmonic generation from periodic arrays of arbitrary shape plasmonic nanostructures: a surface integral approach
Olivier Martin, Jérémy Butet, Benjamin Gallinet, Krishnan Thyagarajan
A surface integral formulation for the second-harmonic generation (SHG) from periodic metallic-dielectric nano-structures is described. This method requires the discretization of the scatterers' surface in the unit cell only. All the physical quantities in ...
