We investigated different methods to engineer efficiently a planar defect between two artificial opals. The samples were characterized by atomic force microscopy, scanning electron microscopy and specular reflection spectroscopy. They presented pronounced defect modes within the photonic stopband. These architectured structures were applied to the manipulation of nanocrystals fluorescence and to the detection of bisphenol A traces.
