Custom Material Optical Index Perturbation in CHARGE

I am attempting to modify the index change due to carrier concentration calculated with the FEEM solver in CHARGE but I don't see a tab for this option like I do in MODE and FDTD as seen in this link:

Does this mean we have to export the results to MODE and solve it that way instead?

    Thanks for reaching out. In FEEM you would need to calculate the index change due to carrier concentration or temperature manually and then import it into an nk import object. Here is an example of this approach which also includes a script for converting temperature to index change. As you suggested, in MODE you can rely on the simulation to estimate the index change which would be more convenient.
