Повний текст джерелаDirect Laser Writing (DLW) has been an exponentially growing research field during the last two decades, by providing an efficient and robust way to directly address three dimensional (3D) structures in transparent materials such as glasses using femtosecond laser pulses. It exhibits many advantages over lithography technique which is mostly limited to two dimensional (2D) structuring and involves many fabrication steps. This competitive aspect makes the DLW technique suitable for future technological transfer to advanced industrial manufacturing. Generally, DLW in glasses induces physical changes such as permanent local refractive index modifications that have been classified under three distinct types: (Type I, Type II & Type III). In silver containing glasses with embedded silver ions Ag+, DLW induces the creation of fluorescent silver clusters Agmx+ at the vicinity of the interaction voxel. In this work, we present a new type of refractive index change, called type A that is based on the creation of the photo-induced silver clusters allowing the creation of new linear and nonlinear optical waveguides in silver containing glasses. Various waveguides, a 50-50 Y beam splitter, as well as optical couplers, were written based on type A modification inside bulk glasses and further characterized. On the other hand, a comparison study between type A and type I waveguides is presented, showing that finely tuning the laser parameters allows the creation of either type A or type I modification inside silver containing glasses. Finally, based on type A near-surface waveguides, a highly sensitive refractive index sensor is created in a 1 cm glass chip, which could exhibit a pioneer demonstration of double sensing refractive ranges. The waveguiding properties observed and reported in the bulk of such silver containing glasses were transposed to ribbon shaped fibers of the same material. Those results pave the way towards the fabrication of 3D integrated circuits and fiber sensors with original fluorescent, nonlinear and plasmonic properties that are not accessible using the standard type I modification

Повний текст джерелаL’infrarouge moyen présente un grand intérêt pour de nombreuses applications dans des domaines variés comme la médecine, la biologie, l’environnement ou encore l’astronomie. Il y a donc un besoin de sources et de dispositifs fonctionnant dans cette bande de longueur d’onde s’étendant approximativement de 2 à 20 µm. L’élaboration de ces dispositifs passe par le développement de matériaux transparents dans l’infrarouge moyen puis par la fonctionnalisation optique de ces matériaux. Dans le cadre de cette thèse de doctorat, nous nous proposons d’étudier la fabrication de composants dans un verre d’oxyde de métaux lourds (baryum, gallium, germanium : BGG), dont l’intérêt est la combinaison d’une bonne transmission jusque dans l’IR moyen (de ~350 nm à ~5 µm) et de bonnes résistances mécanique et chimique. La technique utilisée pour la fonctionnalisation optique de ce verre est l’inscription directe par impulsions ultra courtes. Cette dernière permet de modifier localement – et de manière permanente – un matériau par la focalisation d’impulsions d’une durée de l’ordre de quelques dizaines ou centaines de femto secondes, générant des intensités lumineuses très importantes et permettant l’absorption non-linéaire d’une partie de l’énergie du faisceau laser. Le caractère non linéaire de l’interaction permet l’inscription de structures tridimensionnelles dans le volume du matériau. Grâce à cette technique, on peut notamment fabriquer des guides d’onde, des canaux de microfluidique et des motifs fluorescents pour ne citer que quelques exemples. Nous rapportons dans cette thèse une étude détaillée de l’inscription par laser femtoseconde dans différents types de verres BGG. Nous montrons qu’il est possible d’avoir un changement d’indice positif élevé, permettant la formation de composants à base de guides d’onde pour l’IR moyen. En particulier, nous présentons des résultats de mesures sur des guides d’onde et des coupleurs dans l’IR moyen, inscrits dans un verre BGG et dans la silice. Un autre type verre, dérivé des BGG et dopé en ions argents, est également étudié dans le cadre de l’inscription par laser femtoseconde. Comme il a été observé dans d’autres types de verres d’oxydes, les ions argent modifient l’interaction laser matière et apportent des propriétés spécifiques à l’argent : fluorescence, génération de seconde harmonique et résonance de plasmons de surface.
The mid-infrared region is of great interest for many applications in various fields such as medicine, biology, environment and astronomy. Therefore, there is a need for developing sources and devices operating in this wavelength region, spanning approximately from 2 to20 µm. The development of these devices involves the development of mid-IR transparent materials and then the optical functionalization of these materials. In the framework of this PhD thesis, we propose to study the fabrication of components in glass of heavy metaloxides (barium, gallium, germanium: BGG), whose interest is the combination of a good transmission (from ~350 nm to ~5 µm) and good mechanical and chemical resistances. The technique used for the optical functionalization of this glass is direct inscription by ultra-short pulses. This technique allows a local and permanent modification of a material by focusing pulses of a duration of a few tens or hundreds of femtoseconds, generating very high light intensities and allowing the non-linear absorption of the laser beam energy. The non-linear nature of the interaction allows the inscription of three-dimensional structures in the bulk. Thanks to this technique, we can produce waveguides, microfluidic channels and fluorescent patterns, to name but a few examples. In this thesis, we report a detailed study of femtosecond laser inscription in different types of BGG glasses. We show that it is possible to have a high positive index change, allowing the formation of waveguide-based components for mid-IR. In particular, we present measurements results on waveguides and couplers in the mid-IR, embedded in BGG glass and fused silica. Another type of glass derived from BGG and doped with silver ions is also studied with the femtosecond laser inscription. As observed in other types of oxide glasses, silver ions modify the laser-matter interaction and provide silver-specific properties such as fluorescence, second harmonic generation and surface plasmons resonance.
