ABSTRACT
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 be taken into account. To control dispersion, the anticrossing point can be shifted by the change of the PC waveguide parameters. An example of a waveguide is presented with vanishing second- and third-order dispersion.

    We show that lattice mismatched bilayer graphene can realize robust one-dimensional wires. By considering a single domain wall, where the masses of the Dirac electrons change their sign, we establish a general projection principle. This determines how the existence of topological zero-energy...
