Modal Index calculations
I have done 3D transverse mode calculations and found the number of Modes present and its modal index using the ADI Method.
Now my queries are,
1. Is the modal index we obtained using the above-mentioned simulation process is the effective refractive index of the mode in a designed waveguide?
2. Apart from the Modal Index value, another value is also provided besides that, what is that value called? Please do find the attachment.
3. The comments in the Polarization is given as SVect TE (or TM), here what does SVect means?
4. Finally, is the modal index value is obtained by the depth-wise calculation of the “Designed Cladding-Core-Substrate” waveguide structure? Is it possible to do effective index calculation along the lateral direction?
Please do let me know if my questions are not clear.
I am very new to the FDTD software, and it will be helpful with your positive reply.
