Abstrakt: We predict that singular photonic Bloch modes with extremely narrow bandwidths occur in dual-periodic dielectric multilayer structures. The electromagnetic field of these modes is shown to be strongly localized around the troughs of undulated periodic dielectric structures, which leads to an extraordinary high-Q value effect in the dual-periodic one-dimensional photonic crystals. We also propose several real systems suitable for experimental confirmation of the features predicted. © 2001 American Institute of Physics. [ABSTRACT FROM AUTHOR]
