本文利用功率流方程研究了塑料包层石英光纤和有机玻璃包层PMMA光纤中的模式耦合状态。耦合系数的确定，通过扩展我们以前报道的计算方法的窄光束发射的分布比相应的稳态分布更宽。结果表明，有机玻璃包层PMMA光纤比塑料包层石英光纤具有更强的模式耦合。因此，用于实现稳态分布的光纤长度对于有机玻璃包层PMMA光纤比对于塑料包层二氧化硅光纤短。
Using the power flow equation, the state of mode coupling in plastic-clad silica fiber and organic glass-clad PMMA fiber is investigated in this article. Coupling coefficients are determined by extending our previously reported calculation method to the narrowing beams that are launched with distributions wider than the corresponding steady state distributions. It was found that the organic glass-clad PMMA fiber showed stronger mode coupling than the plastic-clad silica fiber. Consequently, the fiber length for achieving the steady state distribution was shorter for organic glass-clad PMMA fibers than for plastic-clad silica fibers.
