In FDE sofware, we can directly get the effective mode area of a strip waveguide. However, for unsymmetric waveguide (width larger than height), how to get the effective mode dimension in both x and y axis?

As long as FDE can simulate the waveguide mode, you should be able to calculate the mode area. At least you can export the data and calculate it by your self using script. I did not see any thing to prevent from doing this. Please try.

Hi, as attached, how to extract the electrical intensity data in the line z=0?

[Guilin Sun]

you can use

EE=getresult("mode1","E");

E2=EE.E2;

Ex=EE.Ex;

x=EE.x;

where Ex (and Ey,Ez) are 4D matrix of xyz and f.

then you can find x=0 intensity, such as

E_line=E2(find(x,0),:,:,:);

In your case, you can use E2(:,:,find(z,0),1) where z=EE.z

Please try.
