Hi

is it the "effective mode index" neff ? you are looking for

in which case try an indexed search on the rfug.pdf doc
good luck

Hi!
What should I put in the "Global variable to evaluate" dialog box in order to get the effective refractive index as an output? I cannot find the name of the variable...
thanks a lot!

Hi

If you operate in the "parametric solver" mode, you can define your "parameter" value as the frequency variable (or a value that drives the frequency though an expression)

Then you can scan over frequency or optical wavelength

Good luck

Hello,
I try to calculate the effective index of photonic crystal fiber. So for comsol I know only that I can set a single value of wavelength.
Is it possible with comsol to define a range of wavelengths (with to define its step ) in order to calculate the effective index?

Thanks in advance,
Ilyes
