| 摘 要： | 理论推导了保偏光纤(PMF)对轴角度、起偏器起偏角与相干域检测信号的关系,仿真分析表明,对轴误差越大,引起的偏振耦合越大.根据白光干涉原理,采用Michelson干涉仪光程补偿的方法,实验研究了偏振耦合强度与对轴角度之间的关系,并根据测量的耦合强度数据计算出对轴角度.

| Abstract: | The relationship between the interference signal and the alignment angle is derived theoretically for the polarization maintaining fiber(PMF).And the theoretical simulation is investigated correspondingly.It is shown that the larger the alignment angle is,the greater the intensity of polarization coupling becomes.The method for precisely measuring the alignment angle between two PMFs is also presented.By using a scanning Michelson interferometer to compensate the optical path difference(OPD) bas... |
