Abstract
Using chemical and physical purification method, Ge20Te20Se60 and Ge20Se80 glasses with high transmittance were prepared, respectively as the core and cladding material. Based on the rheological properties of chalcogenide glass and the dependence of viscosity to temperature, the fibers were prepared with completed core-clad structure, low structure defect and better ovality by flat mould extrusion method. This study shows that fiber loss decreased obviously after glass purification. As a result, the average fiber loss reduces to 8.5 dB/m, and the lowest loss decreases to 6.8 dB/m in 4.25 μm wavelength. Using the flat mould extrusion method, the crystallization tendency of the Ge20Te20Se60 glass composition could be avoided. The resulting Te fiber with a clear core-cladding interface, good uniformity and low loss value, meets the demand for ideal transmission and sensor of infrared light, and has a potential application value in the far infrared optical field.
