Hello Niki,
I take advantage of this already opened post to ask you a further question. How does Zemax calculate the irradiance from a zbf file exported from Lumerical? In zeemax I get irradiance in the order of 1e12 W/mm^2 (really high) by using field with unitary amplitude in Lumerical. This is not making much sense to me.
Thank you,
Lorenzo
