International audienceEffects of multiple drawing operations on As38Se62 and Ge10As22Se68 chalcogenide microstructured optical fibers (MOF) are investigated. Fabrication of small-core single-mode chalcogenide MOF's with 3 rings of holes necessitates a two-step drawing operation which may conduct to additional optical losses, as compared to single-step processes. Thus, glasses with high stability against crystallization are required. With this respect, Ge10As22Se68 single-mode microstructured optical were obtained with optical losses equal to 1 dB/m at 1.55 µm and lower than 1 dB/m at 3.0µm. Core diameter is as small as 4-6 µm
