Hello Romala,
let me address each of your points in turn:
- The modal index is the effective refractive index as seen by that mode in that structure.
- The other value you are referring to is the 0.00000 or the SVect TE? The 0.00000 is the imaginary potion of the modal index, in this case the modal index is entirely real. The SVect TE is the polarization of the mode.
- SVect indicates you ran a semi-vector simulation, if you had of run the Full vector it would be indicated by an FVect.
- You have performed a modal analysis over the area of the input plane as this is what will perform the injection. As it stands you can only have a Z-directed input plane and as such your modal analysis will be confined to the XY plane. We are working on introducing X and Y directed input planes with arbitrary tilt in the next release of the product.
