Directional Coupler

I noticed the Directional Coupler specs, as designed in the toolbox, are different from your paper's results.

For example. the paper recommends that L1 and L2 for a TE waveguide should be 12.4 and 4.6 microns respectively. The toolbox appears to use 33 and 0.55 microns respectively.

Is there any particular reason for the difference? The documentation has a broken link where "more information" is provided.

Hi @smartalecH,

Sorry I didn't notice your post earlier. Can you let me know which device you are referring to specifically, and where the link is missing?

Yes, the broadband directional coupler (specifically the TE mode device).

The wiki says the following link should provide more info:
