Large-scale sub-100 nm compound plasmonic grating arrays to control the interaction between localized and propagating plasmons

Olivier Martin, Thomas Gerd Siegfried, Arash Farhang

Compound plasmonic resonances arise due to the interaction between discrete and continuous metallic nanostructures. Such combined nanostructures provide a versatility and tunability beyond that of most other metallic nanostructures. In order to observe suc ...

Theory of molecular excitation and relaxation near a plasmonic device

Olivier Martin, Thierry Laroche

The new optical concepts currently developed in the research field of plasmonics can have significant practical applications for integrated optical device miniaturization as well as for molecular sensing applications. Particularly, these new devices can of ...

Spatial symmetries in nonlocal multipolar metasurfaces

Olivier Martin, Karim Achouri, Ville Tuovi Tiukuvaara

We propose a framework that connects the spatial symmetries of a metasurface to its material parameter tensors and its scattering matrix. This provides a simple and universal way to effortlessly determine the properties of a metasurface scattering response ...

Homogenization and Scattering Analysis of Second-Harmonic Generation in Nonlinear Metasurfaces

Olivier Martin, Karim Achouri, Jérémy Butet, Gabriel David Bernasconi

We propose an extensive discussion on the homogenization and scattering analysis of the second-order nonlinear metasurfaces. Our developments are based on the generalized sheet transition conditions (GSTCs) that are used to model the electromagnetic respon ...

A Universal Law for Plasmon Resonance Shift in Biosensing

Olivier Martin

We drive an explict expression for the resonance frequency shift for a subwavelength plasmonic nanocavity upon the adsorption or trapping of a single nanoparticle using rigorous perturbation theory. It reveals a simple linear dependence of the resonance fr ...

Probing Nanogap-Dependent Plasmonic Coupling in Gold Nanoparticle Superlattices by Scanning Tunneling Microscopy Induced Light Emission

Olivier Martin

Plasmonic nanogaps can support confined and enhanced electromagnetic fields. In this work, we use scanning tunneling microscopy-induced light emission (STM-LE) to study the localized surface plasmon resonance of gold nanoparticle superlattices, which consi ...

Reusable plasmonic substrates fabricated by interference lithography: a platform for systematic sensing studies

Olivier Martin, Thomas Gerd Siegfried

Surface-enhanced Raman scattering (SERS) has become increasingly popular in the scientific and industrial communities because of its analytical capabilities and potential to study fundamentals in plasmonics. Although under certain conditions extremely high ...

Resonant optical antennas

Olivier Martin

We have fabricated nanometer-scate gold dipole antennas designed to be resonant at optical frequencies. On resonance, strong field enhancement in the antenna feed gap leads to white-light supercontinuum generation. The antenna length at resonance is consid ...

Teaching optics to a machine learning network

André-Pierre Blanchard-Dionne, Olivier Martin

In this Letter, we demonstrate how harmonic oscillator equations can be integrated in a neural network to improve the spectral response prediction for an optical system. We use the optical properties of a one-dimensional nanoslit array for a practical impl ...

Does the real part contain all the physical information?

Olivier Martin

Polarisation charge formed on nanostructure surfaces upon optical excitation provides a useful tool to understand the underlying physics of plasmonic systems. Plasmonic simulations in the frequency domain typically calculate the polarisation charge as a co ...

Optical interactions in a plasmonic particle coupled to a metallic film

Olivier Martin

The interplay between localized surface plasmon (LSP) and surface plasmon-polariton (SPP) is studied in detail in a system composed of a three-dimensional gold particle located at a short distance from a gold thin film. Important frequency shifts of the LS ...

Prospects of resonant optical antennas for nano-analysis

Olivier Martin

Suitably shaped metal nanostructures act as resonant optical antennas that efficiently collect light and confine it to a subwavelength volume. Vice versa, light emission from nano volumes can be enhanced by coupling to antenna structures. We give a short i ...

Optical forces and torques on realistic plasmonic nanostructures: a surface integral approach

Olivier Martin, Jérémy Butet

We develop a novel formalism to calculate the optical forces and torques on complex and realistic nanostructures by combining the surface integral equation (SIE) technique with Maxwell's stress tensor. The optical force is calculated directly on the scatte ...

Mode-Selective Surface-Enhanced Raman Spectroscopy Using Nanofabricated Plasmonic Dipole Antennas

Olivier Martin, Holger Fischer

Mode-selective surface-enhanced Raman spectroscopy (SERS) is demonstrated using plasmonic dipole antennas fabricated with electron beam lithography. An similar to 10x change of the relative enhancement between two different Raman modes is observed when the ...

Studying the different coupling regimes for a plasmonic particle in a plasmonic trap

Olivier Martin, Jeonghyeon Kim

Plasmonic antennas improve the stiffness and resolution of optical tweezers by producing a strong near-field. When the antenna traps metallic objects, the optically-resonant object affects the near-field trap, and this interaction should be examined to est ...

Quantifying Fano properties in self-assembled metamaterials

Olivier Martin

Fano resonances in metamaterials can be explained by the coupling between different modes sustained by the meta-atom. While the associated spectral features are usually quite easy to identify for top-down metamaterials, thanks to the deterministic arrangem ...

Quadrupolar susceptibility modeling of substrated metasurfaces with application to the generalized Brewster effect

Olivier Martin, Karim Achouri, Ville Tuovi Tiukuvaara

We derive generalized sheet transition conditions (GSTCs) including dipoles and quadrupoles, using generalized functions (distributions). This derivation verifies that the GSTCs are valid for metasurfaces in non-homogeneous environments, such as for practi ...

Hybrid metasurfaces for light processing

Olivier Martin, Andrei Kiselev, Sergejs Boroviks

We explore the optical effects that result from the combination of two classes of materials: plasmonic metals with a dominant electric response - combined with high index dielectrics - with a magnetic response. Their interaction leads to complex spectral r ...
