Simulate the article accurately

hi.

I want to completely simulate the “Analysis of Independent Strain-Temperature Fiber Bragg Grating Sensing Technique Using OptiSystem and OptiGrating” article.

If anyone can help me out in the full simulation of this article, especially in the optigrting section and get accurate charts,
Also, explain the simulation process< I’d appreciate it.
