熔融拉锥系统中氢气加热源的表征
he Characterization of Hydrogen Heating Source in Fused Taper Biconical System
首先利用K型热电偶测量氢气加热源的温度场分布，然后在氢气流量190sccm，拉伸速度0.1mm/s，不同光纤与加热烧嘴间距下熔拉单根光纤，通过软件监控直接获得附加损耗EL合格（EL<0.1dB）的范围。将EL合格条件下拉制的单根光纤用U型石英基板包装，利用金相显微镜测量光纤的直径变化，直径转化为半径，得到光纤形状变化曲线，并在理论模型和体积守恒定律的基础上，利用定积分法求体积确定有效加热宽度W。综合以上，得到氢气加热源的有效工作范围及有效加热宽度。
In this paper，the temperature distribution of hydrogen heating source was measured by K type thermocouple first. then single optical fiber was tapered at 190sccm hydrogen flowing and speed 0.1mm/s. During this process,the range of qualified excession loss(EL<0.1dB) was obtained by software supervision. The tapered optical fiber which EL was qualified was packed by quartz substrate. Next,the diameter of tapered optical fiber was measured by metallographic microscope. The diameter was changed into radius,then the shape of tapered optical fiber was acquired. According to the law of volume conservation and theoretical model of fiber optic radius changes, the effective heating width was confirmed with the mean of definite integration.. Based on the above,effective working range of hydrogen heating source and the effective heating width was achieved.
