Abstract :
Shear discontinuities in photonic crystals are a new type of defect which can support guided modes. We analyze the guided mode properties, including dispersion diagrams and group velocity dispersion, dependence of the confinement on the shear shift and shear position and the coupling between two shear discontinuity wave guides.
