Scattering states map and reflectance spectra of G(A2B4)6structure. (a) Calculated electric field intensity distribution of TM modes in G(A2B4)6 structure with a linear gradient in refractive index (△n = 16%). Inclined white lines are shown as indicators of the miniphotonic band inclination. One can observe the formation of the photonic WSLs confined between two minigaps. (b) Measured and simulated reflectance spectra of the structure and the input Gaussian pulse (red dotted line) in frequency domain.
