Description
Summary:Effects of multiple drawing operations on As sub(38)Se sub(62) and Ge sub(10)As sub(22)Se sub(68) 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, Ge sub(10)As sub(22)Se sub(68) single-mode microstructured optical were obtained with optical losses equal to 1 dB/mat 1.55 mu m and lower than 1 dB/m at 3.0 mu m. Core diameter is as small as 4-6 mu m.
