Will it be possible to model Transmission spectrum of Tilted FBG Using Comsol Multiphysics?

17 June 2025 0 10K Report

I would like to know wether it is possible to model core to cladding mode coupling using COMSOL.If yes..2D or 3D geometry or are there any particular boundary conditions to be defined.If no ..any other optical simulation tool to simulate the mode coupling from core to cladding
