Hi,
Why not trying to use "parametric solver"!!
But this : "So basically I want to integrate the product of poynting vector for the fundamental mode @ wavelength 1 and poynting vector for the fundamental mode @ wavelength 2 for the same structure." is a bit not clear!!
You want to integrate the product of the same parameter (Poynting vector) but each one of them is in different solution!!??
