grating based coupler
Posted Apr 16, 2013, 3:56 AM EDT 0 Replies
I am trying to simulate a four port grating-based coupler (or filter) by comsol 3.5 but I have some problems :
first : I used port condition for 4 ports that one of them is in-port but I don't know where I should enter the input (in which part )?
second : I don't know which kind of input I should apply?
third : I need to get outputs in three other ports ,so which kind of solver I should use and how can I see the output figures?
I really need help, can anyone guide me?
I attached the figure
