摘要
本文描述的单模光纤参数测量的远场法具有一次实验便可确定单模光纤归一化频率、纤芯直径和数值孔径这三个主要参数之特点.本文给出了远场法的理论推导、实验方法和实际光纤的测量结果.
The three main parameters,the normalized frequency (V),the core diameter(2a)and the numerical aperture (NA)of single mode fibers are determined by observation of the far-field pattern. The theoretical analysis,the system of experiment,the method of measurement and the results of measurement were proposed in this paper.
