1. So what is the recommended half-width for a rectangular transverse profile? I have just taken this 60nm half-width from an example.
Again, for my system what will be the better source (Gaussian transverse or rectangular transverse profile)?
2. If I continue the simulation with the above-attached design (where the rectangular transverse source is normal to the length of the nanowire), I am getting the wrong transmission spectra. An image of the obtained transmission spectra is uploaded. Please check the image file and tell me how will I get the right transmission spectra (I have also uploaded the correct spectra from a reference)
