Abstract

It is shown that electromagnetic energy can be localized to defect regions bounded by parallel planar walls perpendicular to the stack surface in Bragg stacks of two-dimensional photonic crystals. These regions produce larger bandgaps than single-photonic-crystal slabs. Group velocity and dispersion relations can easily be tailored by choice of the proper geometry and materials. Results indicate that such photonic crystals might facilitate photonic trapping and storage together with advanced photonic manipulations.
