International audienceTellurium based glasses have been studied for their optical properties in the far infrared region. New glasses, in the system Ge-Te-AgI, present a very good thermal stability. Indeed, for the first time, no obvious crystallization peak is observed in tellurium based glasses. Then, fibers have been drawn showing interesting optical losses and quite large transmission in the mid-infrared. So, these glasses are good candidates for the elaboration of single mode fibers able to detect the CO2 signature at 15µm for the ESA Darwin project
