Keywords:Photonic crystal waveguides, Circular polarization singularities

High transmission via sharp bends has been demonstrated in honeycomb and triangular lattice photonic crystal waveguides. Here we demonstrate that the bend transmission is strongly dependent on the spatial distribution and brightness of circular polarization singularities in the waveguides.
