The glasses and ceramics laboratory at UR1 presents an important knowledge of exotic glasses without silica, for example: fluorides, phosphates, chalcogenides. In the past decade, this team has developed a great experience of chalcogenide glasses, in their synthesis and purification, their shaping, and also the study of optical properties, putting forward the possibility to obtain non-linear effects 1000 times higher than in silica glasses. In SUPUVIR the goal is to synthesize high purity chalcogenide glasses and fibers transparent in the IR range. UR1 and PERFOS (the R&D plateform of photonics Bretagne) have recently developed a new technique to make low loss microstructured chalcogenide optical fibers.
