Firstly, we get the corresponding chirping parameter of the modified nonlinear Schrödinger equation by use of a complex envelope traveling-wave ansatz. Secondly, substituting this chirping parameter the modified nonlinear Schrödinger equation has been reduced to an elliptic differential equation with a fourth-degree nonlinear term. Thirdly, I apply localized soliton ansatz of the sech type which allows for obtaining W-shaped soliton solution. Lastly, we get the 2-dim and 3-dim graphs of the W-shaped soliton solution by giving specific values to the parameters.
