Hi Anand, 

You would most likely require the MODE solvers for simulating fiber grating. We have an app gallery example on this: Fiber Bragg gratings. The example walks you through how to setup the simulation and obtain the results. You can also download the example simulation file from the article. It uses a solver called EME (Eigenmode Expansion), which is typically used for simulating bi-directional propagation in geometries that support guided modes.

The Ansys Innovation courses offer free introductory videos on these solvers: Learning Tracks (in the Photonics category). I think they will be a good place to familiarize yourself with different solvers.
