Thank you for your reply. The parameters defined in the curved waveguide taper is different from the general p I still have few doubts.

  1. Can common scaler approximation gaussian beam work for larger diameter? Will it be able to generate accurate results or not?
  2. If not, then how do I define NA and other values for my case?  My waveguide dimension and material is different, thus 'n' will be different (n=2.19).
  3. Is theta in the NA =n*sin(theta), is taper angle?
