A1: not sure how did you quantify the LH or RH?

A2: currently the import source is only for monochromatic light. Other wavelength will use that imported profile, which might not be correct. You could import several different wavelengths at the same location.

You could also file a feature request, when you have your source as a function of wavelength: ix.lumerical.com

 

"import source span = 7.5um (in x and y), NA = 0.3"

The source span (and FDTD span) might be a little small, as from the monitor result the fields are cut off, which will cause diffraction.

I strongly suggest to test the single wavelength at this moment.
