摘要：

Photonic crystal waveguide bends are generally designed to follow the crystal symmetry directions. For low angle bends higher propagation losses are typically observed. We present three waveguide bending techniques and the resulting photonic crystal geometries that permit low propagation losses for waveguide directional changes that do not correspond to the symmetry directions.
