(Color) Numerical simulations of the transmission spectra of , , , and TM lattices with , , , and . Certain gaps, labeled FGs, have fractal structure that is not present in the other gaps, labeled TGs.
(Color) The upper (red) and lower (black) edges of (a) the BFG and (b) the BTG as the phase modulations are changed. The structural parameters are the same as in Fig. 1.
The field magnitude vs position . (a) The gap-edge state near the BFG in an TM lattice. The inset shows the state at the same frequency in an TM lattice. (b) The gap-edge state near the BTG in an TM lattice. All structural parameters are the same as in Fig. 1.
(Color) The experimental spectra of , , and TM lattices with identical structural parameters to Fig. 1. The agreement with the FG and TG behaviors in Fig. 1 is evident.
