first, a big thank you to the entire Nazca Team for providing such a powerful tool.
I am a bit confused about how to properly define a waveguide cross-section and then making use of the 2D/3D plot functionality and mode solver. To be a bit more precise I would like to do the following:
a) Define a certain cross section in 2D (e.g. a Si nanowire waveguide surrounded by oxide cladding)
b) (optionally: create a section a waveguide in that cross-section, e.g. a straight)
c) plot the cross-section of that waveguide
d) calculate the effective index of the fundamental mode
I have been trying and searching around a bit but if someone could provide a minimal example of how to do this (or tell me that this doesn’t work) I would be extremely grateful.
