Hi, I am trying to optimize a photonic crystal fiber design with MPB --- Basically the fiber is the common triangular-lattice air holes on dielectric, with large center air core as wave tunnel. Can anybody give some advice on how to find a good fundamental mode of the fiber? Right now what I do is to sweep k_z and calculate bands around the band-gap frequency, then calculate the energy portion within the center air core for each band above the light line(so that is propagating mode), and then pick up the best one with the largest energy ratio in the core. However, it is very tedious. Wondering if there is a better way to locate the fundamental mode in MPB?
Thanks a ton!
