Start by simulating the step index fiber (find it at the model gallery). Then you can start by modifying that model and inserting the air-holes. Finally you can go an insert the liquid crystals. --...

Thank you Mr. Felipe for your response...... I have tried simple models.... I am having doubt regarding creating PML layers and boundary conditions... Is creating a PML necessary thing? I heard from a...

you can always start with 'scattering boundary conditions'. But generally, PMLs perform better.

It depends on how important are the radiation losses for you. In case you do not need to know precisely the radiation losses, then I will go with the Comsol's PML just to prevent spurious reflections...

Thank you Mr. Felipe ... I will proceed with the PML layer itself :)

Hi Uday, Have you obtained the intensity profile for your model? If so, you can see your effective index above it. The real part corresponds to the effective index. It will correspond to the first...
