Scattering states map and reflectance spectra of (A2B4)6structure. (a) Calculated electric field intensity distribution of TM modes in (A2B4)6 structure with no refractive index gradient i.e., △n= 0 (flat miniband situation). A change of color from dark to bright corresponds to the increase in the light intensity. (b) Measured and simulated reflectance spectra of the structure. The schematic illustration of the corresponding DP structure is shown just above the scattering states map.
