About defining a TE/TM mode incidental light in 3D waveguide structure

Hi, everyone.

Since we know we can use a 2D cross-section of waveguide to fine the effective refractive index. Incident light at the designed port can be difined as "Rectangle" with TE/TM mode.

Here I want to do the simulation in 3D model. The type of port is "numeric" while there is no definition for the mode.

After boundary model analysis I got the field distribution in the cross-section.
I wonder whether I can define a TE/TM light to simulate in 3D model.

Thank you so much.

You can use Port>User Defined to specify manually TE and TM modes

About defining a TE mode in 3D waveguide sturcture

Thank you so much for your guidance.

Now I will try to use "user defined " port.
However, if I want to use a 1W TE-polarized incidental light, what should I define on INPUT QUANTITY(like the initial value of electric fields and propogation constant?)

Thanks so much.

hey,
I'm having similar problems. I'm also trying to design a 3D waveguide model. Have you found the solution yet?
