Hi, I am using Physical Optics Propagation and try to compute the coupling into a monomode fiber.

Should I use “Gaussian Waist” as fiber type? I think “Top Hat” is for multimode, right?

And what is “Waist X-Y”, is it the physical diameter onf the fiber core, or the Mode Field Diameter (MFD) of the fiber?

Thanks
