Hi!<\/p>\n

I am having troubles with simulating waveguide couplers. I am attaching my simulation screenshot for your convenience. Basically, when I connect two couplers together (one with coupling ratio of 0.95 and the other with 0.05) I don't have any output at the upper port (port 3) of the latter device when reading it with ONA. If I use a single coupler I can read both outputs with ONA. I am sure this issue has something to do with the fact that the second waveguide coupler has light at both of its inputs (and one of them is phase shifted by pi\/2). I hope you can clarify the origin of this behavior for me. Thank you!<\/p>\n
