Photonic Crystal Waveguides in Triangular Lattice of Nanopillars
Photonic nanopillars waveguides have been analysed. Dielectric nanopillars are arranged in such way that they from a tringular lattice of 2D photonic crystal. Dispersion of the modes depends on the direction of the triangular lattice, Ã-J or Ã-X, in which nanopillars arrays are extended. Light fields are confined within the nanopillars arrays and guided by reflection.
Interaction of 1-row nanopillars waveguides gives origin to the coupling phenomena followed by the splitting of modes, anticrossing effect, folding of modes at the edge of the Brillouin zone and mini stopband formation. Transmission spectra calculated by FDTD method completely reflect peculiarities of modes dispersion, showing up to 80% transmission for a realistic SOI nanopillar structure.
