Eco-Friendly Ge-Se Chalcogenide Fiber Extrusion Preparation and Supercontinuum Generation
In order to fabricate an arsenic-free infrared chalcogenide optical fiber,two kinds of high purity glass samples, i.e., Ge20Se79Te1 and Ge20Se80, are prepared by the melt-quenching method and dynamic vacuum distillation purification process. Then a Ge-Se fiber preform with ideal core-clad structure is prepared by an optimized peel-off extrusion method. The drawn Ge-Se fiber has an average loss of 4.8 dB/m in the range from 7.5 to 8.7 μm,and has a minimum loss of 3.2 dB/m at 7.7 μm. A flat supercontinuum in the range of 1.5-11.2 μm is generated by using a 17-cm long fiber which is pumped by an optical parametric amplifier, and the relationship among supercontinuum wide, pumping wavelength, and pumping power is obtained.
