From Vincent Brulis: Yes you just need to sum up the field amplitudes. If you want to normalise your vector you simply need to normalise the field coefficients; the normalised vector corresponding to [1.0 + 0j , 0.5 + 0.5j , 0 , 0] is [1.0/sqrt(1.5) + 0j , 0.5/sqrt(1.5) + 0.5j/sqrt(1.5) , 0 , 0]

V.Brulis: Provided that you are only launching light from one end of the Device (either LHS or RHS) then the best way to do this is to export the forward (LHS) or backward (RHS) field profile at the launching end of the Device; this is the equivalent of right-click "\View XY field at..." in the GUI.
