Experimental observations of the radiation pattern of a short multimode fiber with different induced deformations are reported here. Theoretical calculations are also made, based on the assumption of strong coupling between two particular modes of the fiber, and are in good agreement with experiment. We obtain numerical evaluations of the coupling coefficients and excess loss as a function of the amplitude of the deformation, and indications on the requirements to be met in cabling the fibers are derived from the experimental results.
本文报道了具有不同诱导变形的短多模光纤辐射方向图的实验观测结果。基于光纤两个特定模式之间强耦合的假设进行了理论计算，计算结果与实验结果吻合良好。我们得到了耦合系数和过量损耗随变形幅度变化的数值评估，并从实验结果中得出了光纤布线时需要满足的要求。
