This paper implements mathematically rigorous extended trial function algorithm to address cubic–quartic optical solitons in birefringent fibers having Kudryashov’s law of nonlinear refractive index. Three special cases of the power-law nonlinearity parameter are taken into consideration. Bright and singular optical solitons emerge from this analytical scheme.

用扩展的试验函数求古德里阿索夫模型具有时滞的三次-四次光学孤子

本文实现了数学上严格的扩展试验函数算法，以解决具有Kudryashov非线性折射率定律的双折射光纤中的三次方孤子。考虑了幂律非线性参数的三种特殊情况。明亮而奇异的光学孤子从该分析方案中出现。
