Hello,

In the geometry tab, make sure the monitor is centered and set the x span and y span to match the span of the simulation region.

Please see the video to understand more about mode sources:

Monitors:

And yes, the monitors should be larger than the waveguide to capture the entire light distribution around the waveguide boundary.

I would also recommend the following course : Ansys Lumerical FDTD – ANSYS Innovation Courses
