How to decide FDE size in Lumerical software?

Mukund Kumar Singh @Mukund-Singh

16 December 2022 0 1K Report

I am trying to simulate a single mode silicon waveguide in Lumerical FDE solver.

Q) What is the best practice to decide the FDE size for waveguide cross section?

When I am changing the FDE size, number of propagating modes are changing.
