Thank you, Prof. Steven. I've got some ideas about this problem: I see a small down movement of the branch of the dispersion diagram in the Kerr-nonlinear periodic structure. At this moment with (run-k-points...) method I just see this movement when the ampliude of the signal is not big enough. And when I started to simulate the structure without periodical boundary condition I started to observe gap solitons, as you write in your letter. Now I tried to understand where is the scope of applicability of my simulation. Of course it is very important question as well.
Thank you, Alexandr. _______________________________________________ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
