ABSTRACT
We derive a general, analytical, coupled-mode theory for disorder-induced scattering in periodic systems that shows that in the experimentally relevant limit of weak disorder, the reflection in a photonic-crystal waveguide is just as low as in a comparable index-guided waveguide. Moreover, since the photonic band gap also blocks radiative loss, the total scattering loss is reduced, and the total transmission is higher. These general results are verified by direct numerical simulations in an example system. © 2004 American Institute of Physics.

    It is widely believed that a one-dimensional (1D) periodic layered structure with ordinary materials can only have a band gap for certain propagation directions. However, we reveal that a 1D metal-dielectric periodic structure can trap transverse magnetic waves for any angle of propagation in a...

    The electrical properties of nominally undoped and doped (0.1 wt % Cd, I, and Cu) In2Se3 single crystals have been studied in the range 80–400 K. Only iodine doping has been found to have a significant effect on the carrier concentration in In2Se3, raising it from 4.9 × 1017 to 1.6...

    A novel method to measure the strength of Cygel{trade mark, serif} is presented in this paper. The principle of measurement is based on linear variation of photonic band gap with the strength of Cygel{trade mark, serif}. Photonic band gap is obtained using plane wave expansion (PWE) method.

    The authors achieved an isotropic photonic stop band in the blue region near the L point in the Brillouin zone of ZnO inverse opal. This was fabricated by electrochemical infiltration in a polystyrene opal template self-assembled with the meniscus method. In the ZnO inverse opal, the stop band...

    Modes of photonic crystal (PC) line-defect waveguides can have small group velocity away from the Brillouin zone edge. This property can be explained by the strong interaction of the modes with the bulk PC. An anticrossing of “index guided” and “gap guided” modes should...

    We demonstrate the controlled enhancement of photoresponsivity in a graphene photodetector by coupling to slow light modes in a long photonic crystal linear defect cavity. Near the Brillouin zone (BZ) boundary, spectral coupling of multiple cavity modes results in broad-band photocurrent...

    Thin colloidal crystals (or synthetic opals) composed of Stöber silica spheres typically develop cracks when they are utilized to obtain photonic band-gap crystals (or inverted opals). We find that, by sintering the silica spheres prior to assembly of the opal, these cracks can be avoided. We...
