Thank you Mr.Newman
I have following queries-
1) I have attached my design file, will you please tell me that how should I create the structure described in the paper as I am not able to replicate it. Should I create different channel profiles instead of adding different layers in a single profile and please also tell at what position should I add the stubs.
2)It is mentioned that input field is injected in positive x direction but I can not calculate modes in the mode solver because it does not show the position of the waveguide.
Regards
