Dear Dr. Aabid baba,
There is many issue regarding work with Opti BPM. If you look at lesson 14 you will see there is limitation for using wafer size!!(L33mm,W:100 Micro). Also I attached for you before a simulation about 1 MZ waveguides. Here I attached it again. In case of my design i don’t want using diffuse material!!and I m still confused about cladding and core in this case. What do you thunk?
Your Sincerely,
sardar
