Résumé

On-chip stimulated Brillouin scattering is a critical nonlinear optical phenomenon in photonics and optical signal processing. It requires the simultaneous confinement of acoustic and optical fields within waveguides characterized by a high nonlinear refractive index and low surface roughness. Among all types of glass materials, chalcogenide glasses have also been considered well suited for stimulated Brillouin scattering applications, such as for optical delay systems and filters, because of their high nonlinearities, their substantial refractive indices, and their excellent acousto-optical characteristics. In this context, we have investigated novel arsenic-free selenide and sulfide chalcogenide glasses, incorporating bismuth to enhance their optical properties for sustainable photonic devices. Those advancements in Bibased chalcogenide glasses represent a significant breakthrough for infrared photonics, enabling the development of ultrafast optical systems, IR sensing technologies, and supercontinuum generation platforms.
