This work was devoted to unearth W-chirped to the famous Chen–Lee–Liu equation (CLLE) in optical monomode fibres. The results obtained will be useful to explain wave propagating with the chirp component. To attempt the main goal, we have used the new sub-ordinary differential equation (ODE) technique which was upgraded recently by Zayed EME, Mohamed EMA. Application of newly proposed sub-ODE method to locate chirped optical solutions to the Triki–Biswas equation equation. Optik. 2020;207:164360. On the other hand, we have used the modulation analysis to study the steady state of the obtained chirped soliton solutions in optical monomode fibres.

单模光纤中的W optical孤子和Chen–Lee–Liu方程的调制不稳定性分析

这项工作致力于对光学单模光纤中的著名的Chen–Lee–Liu方程（CLLE）进行W线性调频。所获得的结果将有助于解释rp分量传播的情况。为了实现主要目标，我们使用了新的次微分方程（ODE）技术，该技术最近由Mohamed EMA的Zayed EME进行了升级。新提出的次ODE方法在Triki–Biswas方程方程组chi光学解的定位中的应用。视线。2020; 207：164360。另一方面，我们已经使用调制分析来研究单模光纤中chi线性孤子解的稳态。
