本文研究裸光纤光栅在轴向拉力作用下的应变特性,测出高掺杂光敏光纤的杨氏模量为(1.064E+11)N/m~2,给出了它的反射谱随温度变化的实验曲线,测得其受拉力作用时的断裂阈值为1.078N.
In this paper, the strain behavior of bare fiber gratings under axial tensile force was studied. The Young’s modulus of the highly doped photosensitive fiber was found to be (1.064E + 11) N / m ~ 2. The change of its reflection spectrum with temperature Of the experimental curve, measured by the tensile force of the fracture threshold 1.078N.
