Another question : I want to remove the lithium niobate waveguide, keep the slab and put another Si or SiN waveguide below the LN slab.

When I do that, the FEEM simulation doesn't found the mode, is there a way to force the simulation to give the mode that is between the LN and the Si waveguide ? 

I feel like the simulation is searching for a mode in the lithium niobate waveguide and slab, is this true ? If it is, is there a way to change it ? Thank you!!
