I have want to do a sweep and get the relationship about the radius of the bent waveguide and the tranmission.bent 90_1.fsp (445.5 KB)
This above is my simulation.But I find some problem about my simulation.
**1…**First of all,the relationship between the transmission of the monitor(“T”) and the radius looks strange.
In my opinion,the transmission of the monitor(“T”) will not change with the radius of the bent waveguide because the light have not go through the bent waveguide.Where do I make an error?
2…I compare the transmission of monitor(“T1”) with that of monitor(“T2”),which as show below.
I found when the radius is large than 1.5 micrometer,the two curves nearly coincide,which mean that the transmission loss just happen in the first bent waveguide while there is no loss in the second bent waveguide.furthermore,the transmission of monitor(“T1”) and monitor(“T2”) is larger than 1 when the bent radius is larger than 3.5 micrometer.I think it is not right. can you help me solve the two questions. Thanks a lot.
