Slow light and band gaps in metallodielectric cylinder arrays.
We consider two-dimensional three-component photonic crystals wherein one component is modeled as a drude-dispersive metal. It is found that the dispersion relation of light in this environment depends critically on the configuration of the metallic and dielectric components. In particular, for the case of an incident electromagnetic wave with electric field vector parallel to the axis of the c...
متن کاملLarge omnidirectional band gaps in metallodielectric photonic crystals.
Using a finite-difference time-domain method, we study the band-structure and transmission properties of three-dimensional metallodielectric photonic crystals. The metallodielectric crystals are modeled as perfect electrical conducting objects embedded in dielectric media. We investigate two different lattice geometries: the face-centered-cubic ~fcc! lattice and the diamond lattice. Partial gap...
متن کاملPhotonic band gaps of AB3 and B3 structures of metallodielectric spheres
Using the vector-wave multiple-scattering method we have calculated the photonic band structures of AB3 and B3 crystals composed of perfect metal spheres in air. It is shown that AB3 photonic crystal contains a large photonic band gap and B3 photonic crystal has more than one gap when the filling ratio of metal spheres exceeds a threshold. The multiple photonic gaps of the B3 structure are usef...
متن کاملTransparent photonic band in metallodielectric nanostructures
Under certain conditions, a transparent photonic band can be designed into a one-dimensional metallodielectric nanofilm structure. Unlike conventional pass bands in photonic crystals, where the finite thickness of the structure affects the transmission of electromagnetic fields having frequency within the pass band, the properties of the transparent band are almost unaffected by the finite thic...
