【摘要】 本文从单模、单极化(SMSP)光纤的功率耦合方程出发,考虑随机极化耦合的影响,对单模、单极化光纤的极化保持特性进行了分析。结果表明,SMSP 光纤中两极化模的消光比随传播距离的增加趋于一个稳定值,并与单模、单极化光纤中泄漏模的泄漏损耗以及决定导模与泄漏模耦合系数的光纤参量有密切关系。更多还原

【Abstract】 We investigated the polarization-maintaining properties of single-mode single- polariztion optical fibers by analyzing its power coupled equations with conside- ration of random polarization coupling.Our final result shows that the polarization extinction becomes a steady value after long distance transmission,and it is affected by the loss of leaky mode and some parameters of optical fibers which determine the coefficients of polarization mode coupling.更多还原
