To simulate an optical fiber mode source, you can use the tidy3d.ModeSource. This object allows you to solve for the optical modes of a fiber cross-section. You can then include this in your simulation by following the steps outlined in the example.

If you prefer, you can also use the tidy3d.GaussianBeam source instead to approximate the optical mode of the fiber with a Gaussian distribution, as explained in more detail in another example.
