I have build fiber coupler in 3D. And I used Port 1, 2, 3 and 4 as it is described in directional coupler tutorial. In results, under the 3D plots section, by using slice I plot the normE that is coupling from one to another. And in this system I would like to calculate coupling length or coupling coefficient between these two fibers. I used Cut line along the fiber (I used z direction for the fiber length) to plot E profile and find the Lc (coupling length from sindusoidal plot) but it did not seem an effective way to calculate it.
Does anybody know how to Plot Power ratio between these two fiber vs length(z)? I created cut plane under data set but these cut plane covers both fiber at the same time.
Is there any way to create cut planes separately for each fiber at different z and caculate the power on each cut plane by surface integrating power flow, time average, z direction? I tried surface integration in derived values, but couldnt use the value I obtained from cut plane in data set.
Any information would be much appreciated. Thanks a lot. Elif
