Abstract:
We demonstrate an additive manufacturing approach to produce gradient refractive index glass optics. Using direct ink writing with an active inline micromixer, we three-dimensionally print multimaterial green bodies with compositional gradients, consisting primarily of silica nanoparticles and varying concentrations of titania as the index-modifying dopant. The green bodies are then consolidated into glass and polished, resulting in optics with tailored spatial profiles of the refractive index. We show that this approach can be used to achieve a variety of conventional and unconventional optical functions in a flat glass component with no surface curvature.

Abstract:
ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada
There are a myriad of applications for terahertz radiation: security, military radar, product inspection, and telecommunications. These require manipulation of the radiation beyond simple transmission and detection, namely refraction: focusing, defocusing, and collimation. The current state of the art fabrication of terahertz lenses is an expensive and time consuming processes; involving high purity semiconductors and months of lead time. Our project focused on demonstrating that an inexpensive and quick process could reduce the production investment required by more than three orders of magnitude. This process is based on fabrication using a novel gradient index structure produced with polymer-jetting rapid-prototyping machine.

Abstract:
Les cristaux photoniques à gradient (CPG) permettent une ingénierie de leur indice effectif, ce qui offre de nouveaux degrés de liberté pour la conception de dispositifs photoniques. Ils s’appréhendent par l’optique à gradient d’indice (GRIN optics), qui décrit des milieux inhomogènes dans lesquels la lumière ne se propage pas rectilignement. Il est ainsi possible d’envisager tout profil d’indice. Les CPG sont donc particulièrement attractifs pour la miniaturisation des composants optiques, notamment en photonique sur Silicium. Ils sont fondés sur la variation d’un paramètre de la maille élémentaire du cristal photonique (CP); ici, c’est le facteur de remplissage qui varie afin que l’indice effectif du CPG réalise le profil d’indice souhaité. Le but de cette thèse est d’explorer le potentiel des CPG en concevant des dispositifs à gradient d’indice sur la "plateforme" Silicium sur isolant (SOI) aux longueurs d’onde pour les télécommunications. C’est la chaine complète qui va de la conception à la caractérisation du dispositif, en passant par la simulation et la fabrication, qui est mise en œuvre. Nous nous sommes principalement concentrés sur deux instruments typiques de l’optique à gradient d’indice : la lentille de Mikaelian et le Half Maxwell Fish Eye (HMFE). Dans cette thèse, nous proposons une nouvelle méthode d’approximation de l’indice effectif adaptée à la "plateforme" SOI, que nous avons validée en concevant une lentille de Mikaelian (à profil d’indice sécante hyperbolique). Pour de tels dispositifs, il faut en effet tenir compte de deux indices effectifs : celui du mode guidé dans la couche de Silicium et celui du CP. Dans cette méthode, l’indice effectif du CP est d’abord calculé pour remplacer l’indice de la couche du mode guidé ; puis l’indice effectif de cette couche est calculé. Les résultats de simulation obtenus au moyen d’un logiciel commercial (méthode FDTD) montrent que la lentille ainsi conçue satisfait les prévisions analytiques, contrairement à ce que donnent les méthodes couramment utilisées. Nous l’avons alors appliquée au HMFE. Les dispositifs ont ensuite été fabriqués en salle blanche par lithographie par faisceau d’électrons (EBL) et par gravure plasma (ICP). Les différents CPG fabriqués consistent en des trous d’air répartis périodiquement dans la couche de Silicium, dont le diamètre minimal est d’environ 40 nm. Puis, ils ont été caractérisés en deux temps, notamment par microscopie en champ proche (SNOM). L’épaisseur de ces dispositifs est de quelques longueurs d’onde (3 ou 5 λ_0 environ), tandis la largeur de leur tâche focale est proche de la limite de diffraction (0.5 λ_0 environ). Ils fonctionnent sur une plage de longueurs d’onde de 150 nm environ. Les résultats de la lentille de Mikaelian ont été utilisés pour développer un convertisseur de taille de mode (taper) effectif sur quelques longueurs d’onde. Il est dix fois plus court qu’un convertisseur classique. Dans cette thèse, nous montrons aussi comment il est possible d’interpréter la propagation de l’onde EM dans ces composants à gradient d’indice sur "plateforme" SOI au moyen du principe de l’interféromètre multimode. En se propageant, les différents modes accumulent une différence de phase, qui se traduit par un battement qui modifie la distribution du champ EM, conduisant à la focalisation. La longueur caractéristique de ce battement est égale à la distance focale. Tous ces dispositifs sont étudiés pour s’intégrer dans des circuits de photonique intégrée
Gradient photonic crystals (GPhCs) enable the engineering of their effective index, opening up new degrees of freedom in photonic device design. They can be understood through gradient index optics (GRIN optics), which describe inhomogeneous media in which light does not propagate along straight paths. This makes it possible to consider any index profile. This makes GPhCs particularly attractive for the miniaturization of optical components, especially in silicon photonics. They are based on the variation of a parameter of the photonic crystal elemental cell (PhC); here, the filling factor is varied so that the effective index of the GPhC achieves the desired index profile. The aim of this thesis is to explore the potential of GPhCs by designing graded-index devices on the Silicon-On-Insulator (SOI) "platform" at telecom wavelengths. The complete chain from design to device characterization, including simulation and manufacturing, is implemented. We focused on two typical gradient index optics instruments: the Mikaelian lens and the Half Maxwell Fish Eye (HMFE). In this thesis, we propose a new effective index approximation method for the SOI "platform", which we have validated by designing a Mikaelian lens (with a hyperbolic secant index profile). For such devices, two effective indices need to be taken into account: that of the guided mode in the Silicon layer and that of the PhC. In this method, the effective index of the PhC is first calculated to replace the index of the guided mode layer; then the effective index of this layer is calculated. Simulation results obtained using commercial software (FDTD method) show that the lens designed in this way satisfies the analytical predictions, contrary to the results obtained with commonly used methods. We then applied it to HMFE.The devices were then fabricated in the cleanroom by electron beam lithography (EBL) and plasma etching (ICP). The individual GPhCs consisted of periodically distributed air holes in the Silicon layer, with a minimum diameter of around 40 nm. They were then characterized in two stages, notably by near-field microscopy (SNOM). These devices are only a few wavelengths thick (approx. 3 or 5 λ_0), while their focal spot width is close to the diffraction limit (approx. 0.5 λ_0). They operate over a wavelength range of around 150 nm. The Mikaelian lens results have been used to develop a mode size converter (taper), which is effective over a few wavelengths. It is ten times shorter than a conventional converter. In this thesis, we also show how it is possible to interpret EM wave propagation in these graded-index components on the SOI platforms using the multimode interferometer principle. As they propagate, the different modes accumulate a phase difference, resulting in a mode beat that modifies the EM field distribution, leading to focusing. The characteristic length of this mode beat is equal to the focal length. All these devices are studied for integration into integrated photonics circuits

Abstract:
The human eye is a complex optical system comprised of many components. The crystalline lens, an optical component with a gradient index (GRIN), is perhaps the least understood as it is situated inside the eye and as a result is difficult to characterize. Its complex nonlinear structure is not easily measured and consequently not easily modeled. Presently several models of the GRIN structure exist describing the average performance of crystalline lenses. These models, however, do not accurately describe the performance of crystalline lenses on an individual basis and a more accurate individual eye model based on anatomical parameters is needed. This thesis proposes an anatomically correct, individually customizable crystalline lens model. This is an important tool and is needed both for research on the optical properties of human eyes and to diagnose and plan the treatment of optically based visual problems, such as refractive surgery planning. The lens model consisted of an interior GRIN with a constant refractive index core. The anterior and posterior surface was described by conic sections. To realize this eye model, the optical and biometric properties of mammalian lenses were measured and the correlation relationships between these measurements were used to simplify the model down to one fitting parameter which controls the shape of the GRIN. Using this data, an anatomically correct individualizable model of the lens was successfully realized with varying parameters unique to each lens. Using this customizable lens model, customizable human eye models based on measurements of the entire human eye can be realized.

Abstract:
The main goal of this thesis is the numerical and experimental verification of the concept of the structured micro-optical elements fabricated with the modified stackand- draw technique. This technology, based on the well-known method of photonic crystal fibres (PCFs) production, allows the fabrication of nanostructured GRIN microlenses, form birefringent nanostructured materials and diffractive optical elements (DOEs). The principle of operation of the nanostructured GRIN (nGRIN) microlenses as well as the form birefringent nanostructured material can be explained by an effective medium theory (EMT). Both the approach based on the Maxwell-Garnet formula used for a description of nanostructured GRIN microlenses and the second-order EMT needed to account for birefringence properties are introduced. Numerical simulations of a Gaussian beam focusing and collimation (within GRIN microlenses) are performed using a FDTD method. The modelling results show that nGRIN microlenses can be described using the notion of the effective permittivity (or the effective refractive index) also in the case of the Gaussian beam illumination. Futhermore, Gaussian beam propagation within nGRIN microlenses can be approximately described by the paraxial scalar theory of the GRIN medium despite a high refractive index gradient. The concept of a so-called large-diameter nGRIN microlens with a quantised refractive index profile is introduced. Numerical simulations, performed using fast Fourier transform beam propagation method (FFT-BPM), show that focusing properties of the large-diameter quantised nGRIN microlens are similar to the focusing characteristic of the corresponding ideal continuous GRIN microlens. Both simulation and experimental results show that the fabricated large-diameter quantised nGRIN microlens has good chromatic properties in a range 633nm - 850nm. The successful fabrication of the prototype birefringent nanostructured element and a few diffractive checkerboards structures with different feature sizes is also reported. Applicability of the second-order EMT in the case of the fabricated birefringent material is verified both numerically, using the FDTD method, and experimentally. Diffractive patterns produced by DOEs are shown.

Gradient index (GRIN) materials offer the most general manipulation over wave fields of light compared to conventional refractive optics, where the light is deflected by the curved surface. The creative way to implementing GRIN optics is to construct a subwavelength structure with the electromagnetic characteristics that are unavailable via the natural material. This artificial GRIN structure also known as "metamaterial" can be classified into two general categories: film and slab GRIN optics, depending on the propagation direction of light penetrating through or propagating along the metamaterial. In this dissertation, two different purposes of all-dielectric GRIN optics on (1) film: light extraction enhancement of the scintillator; (2) slab: aberration-free focusing using Lüneburg lens, are both investigated. The scintillator made by ceramics like Lutetium Yttrium Orthosilicate (LYSO) possesses higher index of refraction at 1.82 than the surrounding environment, which causes extraction loss due to index mismatching and total internal reflection (TIR) from scintillator to photodetector. A hybrid structure including two-dimensional photonic slab covered by the nanocone structure on the top was devised to recycle the energy loss from TIR and to create an index-matching layer in between. Design parameters of the hybrid structure were optimized by the simulation based on rigorous coupled-wave analysis, and the fabrication of hybrid structure was patterned by nanospheres (for nanocone structure) and laser interference (for photonic slab) lithography, respectively. Reactive ion etching (RIE) facilitated pattern transfer after two separate lithography processes. Finally, the characterization of nanostructured scintillator was performed with the ionizing source. The rest of this research focuses on the implementation of the slab GRIN optics: Nanostructured Lüneburg lens. The Lineburg lens is an aberration-free lens that can perfectly focus light on the opposite edge of the lens area, and such property can be used for light coupling from fiber to waveguide in the Silicon photonics. We designed the nanostructured Lineburg lens on the silicon-on-insulator substrate using effective index of refraction computed by photonic band theory, and the fabrication was carried out by the e-beam lithography and RIE process. The device characterized by near-field scanning optical microscopy exhibited the single focusing behavior under fundamental mode illumination via the intensity map over the lens region. In addition, the bi-foci phenomenon under higher order mode illumination was also revealed in the finite difference time domain simulation, and the ray picture for explaining the bi-foci was also included using Wigner distribution function and Hamiltonian ray-tracings.

Abstract:
This thesis proposes and tests an individually customizable model of the human crystalline lens. This model will be crucial in developing both research on the human eye and driving diagnostic tools to help plan and treat optical issues, such as those requiring refractive surgery. This thesis attempts to meet two goals: first, it will determine whether this new lens model can reproduce the major aberrations of real human eyes using a computational framework. Second, it will use clinical information to measure how well this model is able to predict post-operation results in refractive surgery, attempting to meet clinical standards of error. The model of the crystalline lens proposed within this thesis is shown to be valid, as it is able to both reproduce individual patient's optical information, and correctly predicts the optical results of a refractive surgery of an individual human eye within clinical standards of error.

Abstract:
Ce mémoire présente l'étude d'un capteur chimique à fibre optique à gradient d'indice inversé basé sur la résonance de plasmons de surface. Des dispositifs optiques à prisme ou mettant en jeu des fibres optiques classiques en silice utilisant cette technique de mesure sont déjà commercialisés. L'objectif de notre travail a été de caractériser théoriquement et expérimentalement un nouveau type de fibre optique permettant d'accroître les performances de ce capteur et d'en simplifier l'instrumentation. Un état de l'art des capteurs à plasmons de surface est présenté. Les structures basées sur une fibre optique (unimodale, multimodale) font l'objet d'une présentation détaillée mettant en évidence les caractéristiques des montages employés ainsi que leurs performances respectives. Nous avons cherché à déterminer le profil d'indice de réfraction du cœur de la fibre rendant les angles d'incidence à l'interface cœur-gaine quasiment égaux quels que soient les rayons se propageant dans la fibre. Ceci a été réalisé en utilisant une source lumineuse ponctuelle monochromatique positionnée dans l'axe et à une distance définie de l'entrée de la fibre. Le profil idéal présente un gradient d'indice inversé très proche d'un profil parabolique inversé pour lequel l'indice est minimal au centre du cœur de la fibre. Une description des caractéristiques de cette fibre comprenant l'étude de la propagation des rayons a été réalisée. Le phénomène de plasmon de surface est ensuite décrit, de manière générale puis ses conditions d'excitation dans la fibre employée sont étudiées. Une étude expérimentale et théorique a été menée sur les paramètres les plus influents du capteur (nature et épaisseur du métal, position de la source ...). La présentation de deux applications pratiques (détection de traces de toluène dans un milieu aqueux et étude en temps réel du mécanisme de formation d'une monocouche auto-assemblée) montre les champs d'applications du dispositif optique simple développé.

Abstract:
The development of multi-mode fibre systems has been largely limited by insertion loss and fabrication difficulties when realising even the simplest of components using optical fibres. An alternative technique is to make use of guided wave optics to realise these components. Since these components can be mass produced the main points to be considered in component evaluation are insertion loss and operational capability.

Abstract:
Design and fabrication of an integrated imaging fiber optic probe (IFOP) (comprising a monomode optical fiber which is fusion spliced to a short length of a graded index multimode fiber) for delivery of either a collimated beam or a focused spot to a remote location, has been reported earlier.1 A short section of a multimode graded index fiber (GFL) with quadratic index profile has focusing properties similar to those of spherical lenses and Sclfoc2 graded index lenses manufactured by NSG2. Advantages of GFL over Selfoc lenses include miniaturization, narrower beam delivery for a certain distance and alignment-free lens system since the GFL is fused to the monomode fiber. Applications in areas such as photon correlation spectroscopy3 and fiber optic connectors4 have been evaluated. Variations in the image distance and magnification can be obtained by controlling the length of the GFL and is limited by the properties (namely the refractive index profile) of the GFL under use.

Abstract:
The ion-exchange process is a well established technology for the generation of gradient-index elements /1/. Because of the high achivable refractive index differences and high transparency of the generated elements Tl-exchange is preferred. But beside the toxicity of Tl-containing salt melts and glasses there is a further disadvantage of Tl-GRIN-elements. This is the high chromatic aberration introduced by the Tl-ion.

Abstract:
Substantial progress in optical fiber communication and optical processing has been made. A new class of optical components based on GRIN technology has led to the creation of innovative optical systems. These systems are characterized by packages which are compact, lightweight, and multifunctional. As a result, high optical performances are achieved by means equivalent to or better than conventional classical optics.

Abstract:
Although the ion-exchange technique has been used for more than a century to produce tinted glass and for several decades for glass strengthening it received increasing attention during the last 10 years. This attention arises from demands of integrated optics for low loss, robust and cheep waveguides and microoptic for small sized optical components fitted to miniaturized light sources, detectors and optical fibres as well as to arrays of these components. Today ion-exchanged components as the GRIN-rod lenses and planar microlenses are commercially available. Ion-exchanged branching elements are introduced into optical communication networks.

Abstract:
Gradient-index rod lenses (SELFOC® micro lens)1) have been widely used in medical optics devices, such as an endoscope which is an optical device for visualization in body cavities.2) The basic structure of the gradient-index rod lens of the endoscope is shown in Fig. 1. It consists of two types of gradient-index rod lenses which are called the objective lens and the relay lens. The object is imaged onto the rear face of the objective lens and this image is transfered to the back of the relay lens.
