Can I get group index in fiber for a single wavelength? I am using * step_index_fiber.lms. How to get rid of group index for this file?
The group index is calculated automatically for each mode when the modes are found. You can see them in the Eigensolver Analysis window results:
If you are using an older version of our software you may have to update your software to see this column.
Thanks for your response. I wanted to know how this group index is being calculated at a single frequency as it requires more than one frequency value.
I’m not sure of the exact calculation used, but this is discussed in the topic New automated group index calculation in eigenmode solver of MODE Solutions . From this topic:
Thanks a lot @kjohnson
You’re welcome @sudipkc!
