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.
