Hi, one question concerning this topic:

As I have written, I need to simulate a non linear optical process with circular polarized light. Normally the circular polarized light is simulated with two linear polarized electric fields (Circular polarization and phase convention – Ansys Optics), one shifted with respect to the other.

In linear process we have that the final result will be the sum of the results of the first and second electric field.

But with non linear optical process (for example second harmonic generation) this is not valid, the result will be proportional to (E1+E2)^2 not E1^2 + E2^2 .

Is this thing considered in the simuation?
