By solving the time-independent power flow equation (TI PFE), we study mode coupling in a multimode W-type microstructured polymer optical fiber (mPOF) with a solid-core. The multimode W-type mPOF is created by modifying the cladding layer and reducing the core of a multimode singly clad (SC) mPOF. For such optical fiber, the angular power distributions, the length L at which an equilibrium mode distribution (EMD) is achieved, and the length z for establishing a steady state distribution (SSD) are determined for various arrangements of the inner cladding's air-holes and different launch excitations. This information is useful for the implement of multimode W-type mPOFs in telecommunications and optical fiber sensors.
通过求解与时间无关的潮流方程（TI PFE），我们研究了具有实心芯的多模W型微结构聚合物光纤（mPOF）中的模式耦合。多模W型mPOF是通过修改包层并减小多模单包层（SC）mPOF的芯而制成的。对于这种光纤，针对内包层气孔的各种排列和不同的发射激励，确定了角功率分布、达到平衡模式分布（EMD）的长度L以及建立稳态分布（SSD）的长度z。这些信息对于多模W型mPOF在电信和光纤传感器中的应用很有用。
