摘要
为了制备无砷红外硫系光纤,采用熔融-淬冷法和蒸馏提纯工艺熔制了高纯度的Ge20Se79Te1和Ge20Se80两种玻璃,基于优化的掏心挤压法制备出具有理想芯包结构的Ge-Se光纤预制棒。拉丝后的Ge-Se光纤在7.5~8.7 μm波段的平均损耗为4.8 dB/m,其中在7.7 μm处达到3.2 dB/m的最低损耗。利用中红外光参量放大器作为抽运源,抽运17 cm长的Ge-Se光纤探究谱宽和抽运波长、抽运功率的关系,获得了光谱宽度为1.5~11.2 μm的平坦超连续谱。
Abstract
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.
