Recent Advances in Resonant Waveguide Gratings

Olivier Martin, Benjamin Gallinet, Guillaume Basset, Giorgio Quaranta

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 ...

Less Is More: Enhancement of Second-Harmonic Generation from Metasurfaces by Reduced Nanoparticle Density

Olivier Martin, Jérémy Butet

We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In contrast to expectations, a substantial enhancement of the SHG signal is observ ...

Second Harmonic Generation Dynamics in Plasmonic Nanoparticles

Olivier Martin, Gabriel David Bernasconi, Jérémy Butet

Due to its symmetry properties, second-harmonic generation in plasmonic nanostructures enables the observation of even-parity modes that couple weakly to the far field. Consequentially, those modes radiate less and thus have a longer lifetime. Using a full ...

Silencing the second harmonic generation from plasmonic nanodimers: A comprehensive discussion

Olivier Martin, Gabriel David Bernasconi, Jérémy Butet

The silencing of the second harmonic generation process from plasmonic nanostructures corresponds to the limited far-field second harmonic radiation despite the huge fundamental electric field enhancement in the interstice between two plasmonic nanoparticl ...

Van der Waals MoS2/VO2 heterostructure junction with tunable rectifier behavior and efficient photoresponse

Igor Stolichnov, Mihai Adrian Ionescu, Andreas Schueler, Olivier Martin, Arnaud Magrez, Chen Yan, Emanuele Andrea Casu, Teodor Rosca, Nicolò Oliva, Anna Krammer

Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of mate ...

Mode Coupling in Plasmonic Heterodimers Probed with Electron Energy Loss Spectroscopy

Jürgen Brugger, Olivier Martin, Valentin Flauraud, Duncan Thomas Lindsay Alexander, Gabriel David Bernasconi, Jérémy Butet

While plasmonic antennas composed of building blocks made of the same material have been thoroughly studied, recent investigations have highlighted the unique opportunities enabled by making compositionally asymmetric plasmonic systems. So far, mainly hete ...

Self-Similarity of Plasmon Edge Modes on Koch Fractal Antennas

Olivier Martin, Gabriel David Bernasconi, Jérémy Butet

We investigate the plasmonic behavior of Koch snowflake fractal geometries and their possible application as broadband optical antennas. Lithographically defined planar silver Koch fractal antennas were fabricated and characterized with high spatial and sp ...

Revealing a Mode Interplay That Controls Second-Harmonic Radiation in Gold Nanoantennas

Olivier Martin, Chen Yan, Gabriel David Bernasconi, Jérémy Butet

In this work, we investigate the generation of second- harmonic light by gold nanorods and demonstrate that the collected nonlinear intensity depends upon a phase interplay between di ff erent modes available in the nanostructure. By recording the backward ...

Fano-resonance-assisted metasurface for color routing

Olivier Martin, Chen Yan, Kuang-Yu Yang

Controlling the phase of an electromagnetic field using plasmonic nanostructures provides a versatile way to manipulate light at the nanoscale. Broadband phase modulation has been demonstrated using inhomogeneous metasurfaces with different geometries; how ...

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

Olivier Martin, Benjamin Gallinet, Guillaume Basset, Giorgio Quaranta

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 ...

Surface-to-volume ratio controls the radiation of stratified plasmonic antennas

Christian Santschi, Olivier Martin, Banafsheh Abasahl

Surface plasmons are excited at a metal/dielectric interface, through the coupling between conduction electrons and incident photons. The surface plasmon generation is therefore strongly determined by the accessibility of the surface to the incoming electr ...

Full Color Generation Using Silver Tandem Nanodisks

Christian Santschi, Olivier Martin, Hua Zhao, Chen Yan, Jingwen Zhang, Xiaolong Wang

Plasmonic effects associated with metallic nanostructures have been widely studied for color generation. It became apparent that highly saturated and bright colors are hard to obtain, and very small nanostructures need to be fabricated. To address this iss ...

Strong Improvement of Long-Term Chemical and Thermal Stability of Plasmonic Silver Nanoantennas and Films

Christian Santschi, Olivier Martin, Xiaolong Wang

Silver (Ag) nanostructures and thin films are advantageous plasmonic materials as they have significantly lower losses than gold (Au). Unfortunately, Ag nanostructures suffer from poor chemical and thermal stability, which limit their applications. Here, t ...

Phase Bifurcation and Zero Reflection in Planar Plasmonic Metasurfaces

Olivier Martin, Chen Yan

We introduce a general formalism combining the coupled oscillator model with the transfer matrix method to analyze and engineer the phase of the light reflected from a Fano-resonant metasurface. This method accounts for periodicity and the presence of subs ...

Where Does Energy Go in Electron Energy Loss Spectroscopy of Nanostructures?

Jürgen Brugger, Olivier Martin, Valentin Flauraud, Duncan Thomas Lindsay Alexander, Gabriel David Bernasconi, Jérémy Butet

Electron energy loss spectroscopy is a method of choice for the characterization of both the spatial and spectral properties of localized surface plasmon resonances. The energy lost by the impinging electrons is commonly explained by the Lorentz force acti ...
