This method is working fine but I have a couple of doubts: 1) is the overlap function always using normalsed version of the mode? In case of two mode overlap from MODE the modes both are normalised with field maximum being 1 whereas, if I import the second mode as d-card from the FDTD monitor, this second mode is not normalised to have filed maximum being 1 but I seems function is still giving reasonable results. 2) I tried to free space waveguide1 mode from facet in FDTD and overlap with waveguide2 facet in FDE (as I stated in the previous post), I replicated the same swapping the two waveguides and the results are slightly different, though I would expect the process to be symmetrical. Is this expected for some other reason?
