Study of new tellurite glasses in the TeO2-ZnO-La2O3 (TZL) system for the manufacturing of mid-infrared multimaterial optical fibers and specialty op…
2023
This thesis work was carried out using tellurite glasses from the TeO2-ZnO-La2O3 (TZL) ternary diagram for optical fibers manufacturing. The choice to use this system is motivated by the ambition to improve the transmission of optical signals within oxide glasses for which absorption bands related to OH groups are present in the transparency window. A structural study is first carried out on these glasses by Raman spectroscopy in order to understand the influence of the composition on physicochemical properties (especially on optical and thermal properties) but also to estimate the ability of a vitreous matrix to reorganize when subjected to a thermal solicitation such as the preform-to-fib…
Elaboration of multimaterial optical fibers with electro-optical functionalities
2022
The emergence of multimaterials optical fibers is of tremendous technological interest in photonics to combine the remarkable properties of glasses with those of other materials such as metals or polymers in order to form a fully integrated fiber optical system with multiple functionalities. Among these hybrid fibers, the development of fibers combining both optical signal and simultaneous electrical transport function could bring alternative interesting solution in many fields such as telecommunications, medicine or sensing. The drawing of architectures merging electrical and optical features in a unique elongated wave-guiding structure will enable to develop electro-optical functionalitie…
