▼ Integrated nano-optics and nano-photonics have been very hot
topics in the last two decades, and they play very important
roles in telecommunications, optical interconnectors, integrated
sensing devices, just to name a few. Traditionally, integrated
photonic crystals, Mach Zehnder waveguides interferometers, ring
resonators, gratings are the key elements for integrated photonic
circuits, however, they are bulky and there is a room to decrease
further the functional areas to make more compact integrated
photonic devices. Due to their ability to confine light in
sub-wavelength volumes plasmonic nanoparticles and nanoantennas
can serve as a fundamental link between electronic and photonic
circuits, as they can bridge large size mismatch between the
electronic and optical wave function. Thus, plasmonic elements
can be
utilized to increase the integration density and performance of
active and passive photonic devices, as well as to include new
functionalities and concepts for photonic chips. Therefore, our
goal is to design subwavelength functional areas by utilizing
plasmonic meta atoms to manipulate both farfield and localized
light and integrate these plasmonic functional areas into
dielectric optical waveguides. However, plasmonic materials
suffer from their intrinsic absorption. All-dielectric
nanoantennas, on the other hand, exhibit high radiation
efficiencies, but the lower field confinement
and enhancement which also reduce coupling efficiencies.
Therefore, this thesis is mainly focused on exploiting the novel
applications in integrated photonic devices based on applying the
advantages of plasmonic and dielectric nanoantennas,
respectively. The topics include the integration of plasmonic
nanoantennas on silicon waveguides, such as the spectral band
splitting by using a single Fano nanoantenna, and polarization
demultiplexing by utilizing a dragon fly shape nanoantenna.
Furthermore, this thesis also contains hybrid and all dielectric
metasurfaces in localized light manipulating, biosensing, and
opto-mechanics applications.

▼ Metamaterials are artificial structures consisting of nanoscale building blocks that exhibit properties not found in nature. They have recently shown potential for utilizing nonlinear processes such as second-harmonic generation (SHG) and spontaneous parametric down-conversion (SPDC) in nanoscale applications. Despite the constant progress, metamaterials still lack in terms of conversion efficiency when compared with conventional nonlinear materials that benefit of long propagation lengths and gradual increase of signals via phase matching.
In previous studies of plasmonic metamaterials, the nonlinear properties of metal nanoparticles are enhanced with localized surface plasmon resonances (LSPRs). These resonances have rather short lifetimes leading to high losses typical to metal nanoparticles. Therefore, alternative approaches to realize efficient metamaterials are required.
In this thesis, we present two enhancement methods that are rather well known and studied but not yet fully utilized in nonlinear nanophotonics. The first methods is to utilize collective responses of periodic nanoscale structures known as surface lattice resonances (SLRs) and guided-mode resonances (GMRs). They are associated with narrow spectral features implying the presence of strong local fields and thus enhanced nonlinear responses. Another method to enhance local fields is to couple relevant fields to an external cavity. This method is used in various nonlinear applications such as in optical parametric oscillators (OPOs) and it has been studied also in nanoscale processes.
Here, we investigate how SLRs and microcavities could be used to improve nonlinear metamaterials. First, we perform proof-of-principle studies showing that utilization of GMRs can dramatically enhance SHG occurring in sub-wavelength dielectric gratings. We measure linear and SH response of two silicon nitride gratings and compare the results with simulations based on the nonlinear scattering theory (NLST). As our experiments agree with simulations, we then propose two novel plasmonic metamaterial structures designed for SPDC. The first structure is a metasurface consisting of L-shaped aluminum nanoparticles arranged in a rectangular lattice. The metasurface exhibits SLRs at pump and signal wavelengths resulting in a strong enhancement for the SPDC process where the pump and signal have orthogonal polarizations. Thus, the metasurface mimics a type-I SPDC-crystal which are widely used in quantum optics as photon-pair sources.
Our second design consists of a singly-resonant plasmonic metasurface that is placed inside a microcavity formed with two distributed Bragg reflectors. The cavity is designed to resonate with the pump while the SLR of the metasurface is designed to enhance the local field at the signal wavelength. Our simulations demonstrate a polarization-independent operation where the SPDC is dramatically enhanced at the operation wavelength. This design then can act as either type-0, type-I or type-II nonlinear material, which are all used in quantum…

▼ Electromagnetic metasurfaces, assemblies of nanoantennas with subwavelength lateral size and ultrathin thickness, have emerged as a new frontier in the physics and engineering communities to provide extraordinary light-matter interactions. Metasurfaces transform the electromagnetic waves through local and space-variant phase responses within thin sheets, which open a new route for flat and compact wavefront engineering. Despite the success of bring novel physics, metasurfaces still face some issues which hinder their practical applications and commercialization. In this work, various types of metasurfaces are thoroughly investigated for robust beam engineering with superior characteristics in terms of high efficiency, broad bandwidth and active tunability, while favorable for implementation.; Nanoantenna resonators usually gain limited phase response with poor efficiency due to the large impedance mismatching, leading them non-ideal metasurface components. We propose a plasmonic metasurface with the elements being three-layer cascaded plasmonic loops based on the transmission line theory. Arbitrary inhomogeneous phase control is achievable with efficiency of more than 80%. To bring metasurfaces into visible spectrum without suffering from Ohmic loss, the all-dielectric metasurface is investigated as an alternative with the highest efficiency to date. Complete 360° phase response is captured from the high-index disk resonators by tuning the magnetic and electric resonances through tailoring the disk geometry. The concept of all-dielectric metasurfaces shows great potential to enable practical device functionalities at high frequencies, which motivates us to study it one step further on conformal optical platforms. Ultrathin conformal metasurfaces are demonstrated for invisibility cloaking at 532 nm visible wavelength with superior performances.; To break the inherent narrow-bandwidth limitation accompanied with the rich phase control, truly achromatic metasurfaces are proposed to work in a broad bandwidth without performance degradation. The constitutive layered elements, either plasmonic or dielectric, is to mimic the low-pass filters with linear phase responses but to work at infrared and visible ranges with each layer behaving as a shunt capacitor or a series inductor. A plasmonic collimating lens and a dielectric focusing lens are demonstrated from 5.5μm to 7.5μm and in the whole visible band, respectively, without chromatic aberration.; Moreover, the emergence of two-dimensional materials, such as graphene, provides an ideal platform for ultra-thin metasurfaces with new functionalities. The conducitivity of graphene is widely tunable via chemical doping and electrical biasing. Here taking advantage of the chemical tunability, graphene metasurfaces with gradient index profile are realized by patterning two types of molecules on graphene to manipulate surface waves as desired. In addition, a reconfigurable leaky wave antenna with smart and simply one-dimensional biasing configuration over a graphene sheet is…

▼ Cette thèse est consacrée au développement de modèles semi-analytiques précis pour le calcul numérique de dispositifs nanophotoniques résonants. Il s'agit en particulier de membranes à cristaux photoniques, qui supportent des résonances avec des très grands facteurs de qualité, et d’ensembles composés de plusieurs nano-antennes plasmoniques, qui présentent des résonances avec des faibles facteurs de qualité. La thèse est divisée en deux parties.La première partie présente un modèle semi-analytique pour le calcul des modes supportés par des membranes à cristaux photoniques. Les modes à fuite (leaky modes) supportés par ces membranes structurées sont modélisés comme une résonance Fabry-Perot transverse composée de quelques ondes de Bloch propagatives qui vont et viennent verticalement à l'intérieur de la structure. Ce modèle est appliqué à l'étude des états liés dans le continuum (bound states in the continuum, ou BIC). Nous montrons que le modèle Fabry-Perot multimode est parfaitement adapté pour prédire l'existence des BICs ainsi que leur position dans l'espace des paramètres. Grâce à la semi-analyticité du modèle, nous étudions la dynamique des BICs avec l'épaisseur de la membrane pour des structures symétriques et asymétriques. Dans ce dernier cas, nous étudions des objets présentant soit une symétrie horizontale brisée, soit une symétrie verticale brisée (ajout d'un substrat). Le modèle Fabry-Perot nous permet d’obtenir des informations importantes sur la nature et le comportement des BICs. Nous démontrons que lorsque la symétrie miroir horizontale est brisée, les BICs dus à la symétrie du système, qui existent dans les structures symétriques au point Gamma du diagramme de dispersion, restent des BICs malgré l’absence de symétrie mais changent de nature. Ils deviennent des BICs dus à des interférences destructives entre les ondes de Bloch. La deuxième partie est consacrée au développement d'une théorie modale originale pour modéliser la diffusion de la lumière par des structures complexes composées d'un ensemble de plusieurs nano-antennes. L'objectif est de pouvoir modéliser la diffusion de la lumière par des métasurfaces à partir de la seule connaissance des modes de leurs constituants individuels. Pour ce faire, nous combinons un formalisme modal basé sur l’utilisation des modes quasi-normaux (QNM) avec la théorie multipolaire de la diffusion multiple basée sur le calcul de la matrice de transition (matrice T) d'un diffuseur unique. La matrice T fournit la relation entre le champ incident et le champ diffusé dans la base des harmoniques sphériques vectorielles. Elle contient toutes les propriétés de diffusion intrinsèques à l'objet. Le calcul de cette matrice représente une charge numérique lourde car elle nécessite de nombreux calculs rigoureux du champ diffusé. L'utilisation d'une décomposition modale avec des QNMs nous permet d’une part de rendre une partie du calcul analytique et d’autre part d'apporter une meilleure compréhension physique. Nous dérivons une décomposition modale de la matrice T et testons sa…

▼ This thesis summarises my PhD research towards applying nano-scale dielectric resonators (DRs) to
optical metasurfaces for achieving various functionalities, high efficiency, and reconfigurability. Additionally, the thesis also provides brief introductions to dielectric resonator antennas, plasmonics, and a short review of
optical metasurfaces. The major contributions are briefly summarised as follows:
In Chapter 3, resonance properties of cylindrical nano-scale DRs on metallic substrates are analysed. At
optical frequencies, subwavelength DRs with metallic substrates can support horizontal magnetic dipole resonance, which can be used for efficient coupling of surface plasmons. However, two types of resonance breakdown can occur in such DRs, and the cause for both types are analysed in detail. Of particular interest is the negatively-matched resonance breakdown, which occurs when real parts of the permittivities of a DR and its metallic substrate are negatively matched. The negatively-matched resonance breakdown is undesired for
optical metasurfaces and can be avoided by inserting a low-permittivity dielectric spacer between the DR and its metallic substrate. In Chapter 4, unidirectional launching of surface plasmons based on non-uniform arrays of DRs is proposed and investigated. By comparing the principles of DR-based anomalous reflection and surface plasmon unidirectional launching, it is concluded that the optimal launching can be achieved by avoiding the first-order diffraction. The optimal launching condition is verified with numerical simulations and linear array theory. In Chapter 5, a narrowband plasmonic absorber made of a uniform array of nano-scale DRs on metallic substrates is experimentally demonstrated at visible frequencies. It relies on the surface plasmon standing waves coupled by the locally resonant nano-scale DRs for the high absorption. The simulation and measurement results are presented and analysed with coupled mode theory. In Chapter 6, a mechanically tunable DR metasurface is experimentally demonstrated at visible frequencies. The tunable metasurface is realised by embedding a uniform array of DRs into an elastomeric encapsulation. The transmission responses of the metasurface can be tuned when the encapsulation is deformed with an external strain. Measurement results confirm the predictions of simulations and shows a remarkable tuning range. A Lagrangian model is developed to rigorously analyse the simulation and measurement results. Such a design provides a preliminary concept usable in reconfigurable
optical devices, and after further development can also be potentially commercialised for smart contact lenses. In Chapter 7,
metasurfaces made of metal-loaded DR arrays are proposed to realise the functionality of selective thermal emission. Two metasurface designs are presented. The first design is based on a uniform array of square metal-loaded DRs, which are made of doped silicon. Theoretical and numerical analysis demonstrate stable emission peaking at nearly 8 μm across a wide…

▼ Les avancées récentes en optique à l'échelle nanométrique ont donné naissance à une nouvelle branche de la nano-photonique visant à manipuler la diffusion de nanoparticules, avec de nombreuses applications potentielles en communication optique, en photovoltaïque, pour le développement de nano-antennes, de capteurs, etc. La réponse de nano-diffuseurs est souvent caractérisée en termes de multipoles électromagnétiques dont les ajustements constituent un moyen efficace pour façonner à souhait les diagrammes de rayonnement de particules. En particulier, des interférences destructives entre multipoles de parité spatiale opposée peuvent être exploitées pour annuler la rétro-diffusion d’objets de petites tailles. Cet effet, théoriquement prédit il y a 30 ans par Milton Kerker, permet aujourd’hui de concevoir des particules sub-longueur d'onde diffusant la lumière uniquement vers l'avant, partageant ainsi les principales caractéristiques des sources théoriques fictives utilisées dans le principe de Huygens-Fresnel. Une fois assemblées en réseau périodique bidimensionnel, ces particules, appelées "sources de Huygens", offrent des opportunités uniques dans le développement de composants optiques plats et ultrafins, appelés "métasurfaces", permettant un contrôle arbitraire de la phase, de l'amplitude et/ou de la polarisation de faisceaux lumineux. Ainsi, au cours des dernières années, les métasurfaces de Huygens ont été très largement explorées comme alternative à l’optique traditionnelle pour la conception de surfaces remplissant les fonctions de lentilles, de déflecteurs de faisceau, de vortex optique, d’hologrammes ou d’absorbeurs parfaits. Ces travaux se sont notamment appuyés sur des sources de Huygens anisotropes pouvant être obtenues par les technologies dites ‘’top-down’’. Contrairement aux approches étudiées jusqu'à présent, cette thèse porte sur l'étude de sources de Huygens isotropes. Nous étudions en particulier des particules homogènes, composites ou de types coeur-coquille pour atteindre le régime de Kerker. Nous démontrons la possibilité de façonner le front d'onde de faisceaux optiques en utilisant des systèmes sphériques constitués d’amas de particules diélectriques. Nous présentons également un formalisme multipolaire pouvant être exploité pour optimiser l'absorption de surface de Huygens. Comme fil conducteur de notre projet, les objets que nous étudions sont adaptés aux technologies ascendantes (dite "bottom-up") et pourraient de manière réaliste être obtenue par synthèse colloïdale et procédés d’auto-assemblage, offrant ainsi une alternative aux métasurfaces classiquement obtenues par lithographie.

▼ Light, which provides the human eye with the sense of vision, is the basis for many key technologies used in everyday life, and the advanced control of which also benefits technological progress in other areas. The wavefront and polarization are two important properties of light, or, in general, electromagnetic radiation, that dictate its behavior. The ability to precisely control these properties as a function of time is highly desirable, as it is essential for numerous powerful applications, including imaging, high tech manufacturing, and communications, to name a few. There has been a bulk of work on the manipulation of these properties, but there remains much to be improved in terms of extreme compactification, reduction of power, and increase in speed and precision, as use cases are driven towards untethered, lightweight, and high performance devices. In this thesis, novel devices are presented that dynamically shape wavefront and polarization of light, using new principles of operation and design methods.
Wavefront shaping is achieved using
metasurfaces, in which, recently, there has been significant scientific and technological interest due to their inherent multifunctionality and potential to dramatically reduce the thickness of the optics in a wide range of applications. The challenge, however, in making practical devices with
metasurfaces is the difficulty in fabricating them with large areas. One of the key obstacles in this endeavor is the enormous data density required by the subwavelength resolution criterion imposed over large areas, resulting in giant file sizes for the layout design files describing structures greater than a few hundred microns in diameter. We present a scalable metasurface layout compression algorithm that exponentially reduce the design file size of (by 3 orders of magnitude for a centimeter diameter metalens, and even greater gains in compression for larger sizes) and a route to mass manufacturing of metasurface lenses (metalenses) using stepper photolithography with extremely large areas, up to (but not limited to) centimeters in diameter. Because of what is demonstrated here, the claim that chipmakers will be making lenses of the future (as well as the chips), i.e. the unification of two industries: semiconductor manufacturing and lens-making, is now closer to reality. However, metasurface devices are by themselves static, such that additional steps are required in order to introduce the feature of tunability, such as in focal length or magnification control. To take advantage of the thinness and planarity of metalenses, electrical tuning of lateral motion is essential for focal length and magnification control, which in conventional
optical systems is performed by longitudinal mechanical motion along the
optical axis. A large area, integrated
optical device, no more than 30 microns thick, is presented, which imprints a strain field onto the
optical wavefront, by way of a soft metasurface intermediary, enabling simultaneous control over focal length, astigmatism, and image…

▼ In classical optics,
optical components such as lenses
and microscopes are unable to focus the light into deep
subwavelength or nanometer scales due to the diffraction limit.
However, recent developments in nanophotonics, have enabled
researchers to control the light at subwavelength scales and
overcome the diffraction limit. Using subwavelength structures, we
can create a new class of
optical materials with unusual
optical
responses or with new properties that are not attainable in nature.
Such artificial materials can be created by structuring
conventional materials on the subwavelength scale, giving rise to
the unusual
optical properties due to the electric and magnetic
responses of each meta-atom. These materials are called
metamaterials or engineered materials that exhibit exciting
phenomena such as non-linear
optical responses and negative
refraction.
Metasurfaces are two dimensional meta-atoms arranged as
an array with subwavelength distances. Therefore,
metasurfaces are
planar, ultrathin version of metamaterials that offer fascinating
possibilities of manipulating the wavefront of the
optical fields.
Recently, the control of light properties such as phase, amplitude,
and polarization has been demonstrated by introducing abrupt phase
change across a subwavelength scale. Phase discontinuities at the
interface can be attained by engineered
metasurfaces with new
applications and functionalities that have not been realized with
bulk or multilayer materials. In this work, high efficient, planar
metasurfaces based on geometric phase are designed to realize
various functionalities. The designs include metalenses, axicon
lenses, vortex beam generators, and Bessel vortex beam generators.
The capability of planar
metasurfaces in focusing the incident
beams and shaping the
optical wavefront is numerically
demonstrated. COMSOL simulations are used to prove the capability
of these
metasurfaces to transform the incident beams into complex
beams that carry orbital angular momentum (OAM). New designs of
ultrathin, planar
metasurfaces may result in development of a new
type of photonic devices with reduced loss and broad bandwidth. The
advances in metasurface designs will lead to ultrathin devices with
surprising functionalities and low cost. These novel designs may
offer more possibilities for applications in quantum optic devices,
pulse shaping, spatial light modulators, nano-scale sensing or
imaging, and so on.

▼ Depuis de récentes années de nouveaux composants optiques ont fait leur apparition. Ces composants connus sous les noms de « Méta-optiques » ou encore « Métasurfaces », rendent possible le contrôle et la mise en forme du front d’onde de la lumière permettant alors de mettre en forme n’importe quel faisceau incident et ainsi créer des fonctionnalités optiques classiques telles que focaliser ou dévier la lumière, ou alors des fonctionnalités aux propriétés surprenantes telle que la réalisation de métahologramme dépendant en polarisation. En effet, grâce à l’arrangement périodique de résonateurs de dimensions géométriques sous-longueur d’onde, il est alors possible d’obtenir un contrôle local arbitraire du faisceau incident. Néanmoins, même si de nombreuses applications ont pu être démontré dans la communauté, seuls quelques matériaux se retrouvent être compatibles pour le développement industriel de ces composants. De plus, afin de passer de composant passif à actif, pour la réalisation de composant dynamique, il est nécessaire de passer de matériau diélectrique à matériau semi-conducteur. C’est pourquoi dans ces travaux, nous nous sommes intéressés à l’utilisation d’un matériau semi-conducteur qui est le Nitrure de Gallium pour la réalisation de composants métasurfaciques. Nous présentons alors dans un premier temps une étude numérique des nanostructures utilisées lors de ces travaux. Puis nous montrons comment est réalisée la conception de nos méta-optiques en présentant la méthode de design et les procédés de nanofabrications employés, notamment une nouvelle technique de gravure, compatible uniquement avec les matériaux cristallins et préservant leurs propriétés optiques. Nous exposons ensuite différentes applications où nos composants sont utilisés telles que : la réalisation de métalentilles de large ouverture numérique et de large surface, l’optimisation de réseaux métasurfaciques permettant d’atteindre des efficacités de diffraction supérieur à 80% ou encore la réalisation expérimentale de méta-hologramme permettant de conserver l’information du moment angulaire orbitale du faisceau incident.
In the past years, new optical components have appeared. These components, known as "meta-optics" or "metasurfaces", made it possible to control and to shape the wavefront of the light. This allows the control of any incident beam and the creation of conventional optical functionalities, such as focusing or deflecting the light, or functionalities with additional features such as the possibility of creating polarization-dependent meta-holograms. Indeed, thanks to the periodic arrangement of resonators with sub-wavelength geometric dimensions, it is possible to obtain an arbitrary local control of the incident beam. Nevertheless, even though many applications have been demonstrated in the community, only a few materials are found to be compatible for the industrial development of these components. In addition, in order to pass from passive to active components for the fabrication of dynamic devices, it is necessary to…

▼ This dissertation presents a study of the fundamental
mechanisms of ultrafast mid-infrared laser-solid interactions,
focusing on semiconductors. Laser intensities both above and below
the laser-induced damage threshold are used in this study. Despite
a recent increase in interest in both applications and fundamental
mechanisms, the mid-infrared wavelength regime has hardly been
studied previously with ultrashort pulses.New ultrafast
mid-infrared laser sources allow for increased access to this
regime of laser-solid interaction. An ultrafast, mid-infrared
optical parametric amplifier was designed, fabricated, and
characterized. The construction of this
optical parametric
amplifier has led to many experiments and collaborations, which are
presented in this dissertation.Measurements of single and
multi-pulse laser induced damage thresholds were studied in silicon
as a function of mid-infrared wavelength. Additionally, unique
morphology was studied with a wide array of imaging techniques. The
results of these studies were compared to existing theoretical
models and experiments with near-infrared, visible, and ultraviolet
wavelengths. We find that further modification to existing models
and/or new models are needed to explain the data. Our computational
efforts, while they don’t show good matching to the experimental
data, will contribute to future studies in this area.Experimental
studies and numerical simulations were also performed with
intensity below the laser induced damage threshold. Polycrystalline
zinc selenide is an exciting source of broadband supercontinuum and
high-harmonic generation via random quasi phase matching,
exhibiting broad transparency in the mid-infrared (0.5-20 μm). The
effects of wavelength, pulse power, intensity, propagation length,
and crystallinity on supercontinuum and high harmonic generation
are investigated experimentally using ultrafast mid-infrared
pulses. Observed harmonic conversion efficiency scales linearly in
propagation length reaching as high as 36%. For the first time to
our knowledge, n
2 is measured for
mid-infrared wavelengths in ZnSe: n
2(λ=3.9
μm)=(1.2±0.3×10
-14
cm
2/W). Our n
2
measurement is applied to simulations modeling high-harmonic
generation in polycrystalline ZnSe as an effective medium using
unidirectional pulse propagation simulations. Good matching to the
experimental results is found, and the model suggests the harmonics
are generated by cascaded harmonic generation.
