Dear Onder Thanks for your Reply.
I want to find modes shape in Coupled cavity waveguide (array of point defects), so I have to use big supercell!
I start with a line defect in triangular lattice of holes.I already plot the modes, would you please check the attachment which is a plot of the modes of a line defect in triangular lattice of holes (simulated by MPB and normal resolution ). when I change the size of supercell, I can see more modes in the Gap. (Fig. a to c) If I perform simulation only for big supercell(3a*11a), How could I know which mode has been folded and which one is main propagated mode?
Thanks and Best Regards YingJun YL On 1/10/2013 8:30 PM, mpb-discuss-requ...@ab-initio.mit.edu wrote:

Message-ID: <50ed5838.7040...@gmail.com> Content-Type: text/plain; charset="iso-8859-1"; Format="flowed" Dear Prof. and MPB users For simulating coupled cavities in photonic crystal slab, I have to choose a big supercell (e.g. 5a * 15a in x and y direction respectively). In order to assure the correctness of the ctl file and simulation, I simulate a photonic crystal waveguide by removing a row of holes in trangular lattice of holes in PC. When I use 1a*15a supercell, I can see clearly the Band Gap and guided mode in the gap. But when I use the 5a * 15a supercell, several modes folded in band gap. How can I recognize the guided mode? Seems, my question is a basic question in PBG and photonic crystal, but if any of the respected MPB user can help, it will be highly appreciated.
