Hello Sasha,
I tried that tutorials and get the results. Also find the refractive index tab, but confused with the values shown.
That values of ordinary or extra ordinary R.I or of effective R.I. And to get 2-D results you have to do 2-D simulations or by using the tools which are given on tool bar.
Sorry, I can’t access your file as it designed on different version of optiBpm. I am using optibpm9.0.
Thanks for response.
