Definitely, you can. However, it seems you are simulating a fiber cavity? where the source is located? inside the cavity or outside? dipole or mode source or Gaussian source.

Once you get the E-field from the 3D monitor, you can integrate along Z only. related scripts are

getresult  eg E3D=getresult("monitor","E")

dot operation  Ez3D=E3D.Ez  #Ez

                       E2=E3D.E2; # intensity

                      z=E3D.z

integrate  eg integrate(E2,3,z);

Please search online if you want to get more informtation for each script.
