Dear Damian,
Thanks for your informations!
I didn’t understand very well the meaning of calculate the loss through the effective index… Anyway, I have other doubts:
-Before the simulation, I have a warning, like is attached. But, after that is possible to see the result. But, I don’t know if is it bad or not.
-In this case of design (d-shaped fiber), the analyzes have to be anisotropic?
Best regards,
Juliana.
