Wavelength dependence of equilibrium mode distribution (EMD) and steady state distribution (SSD) in W-type plastic optical fibers (POFs) is investigated in this paper for parametrically varied width of the fiber’s intermediate optical layer and refractive index of the outer cladding. We have shown that with increasing the wavelength EMD and SSD are achieved at shorter W-type POF lengths. This is explained by the rise of the leaky mode losses with increasing wavelength. This facilitates tailoring W-fibers to a specific application at hand at different wavelengths.

波长对W型塑料光纤平衡模式分布和稳态分布的影响

本文研究了W型塑料光纤（POF）中平衡模式分布（EMD）和稳态分布（SSD）的波长依赖性，以分析光纤中间光学层的宽度和外包层的折射率在参数上的变化。我们已经表明，随着波长的增加，可以在较短的W型POF长度上实现EMD和SSD。这可以通过泄漏模式损耗随波长增加而增加来解释。这有助于针对不同波长的手边的特定应用定制W光纤。
