Thank you for your reply. The parameters defined in the curved waveguide taper is different from the general p I still have few doubts.
- Can common scaler approximation gaussian beam work for larger diameter? Will it be able to generate accurate results or not?
- 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).
- Is theta in the NA =n*sin(theta), is taper angle?
