Abstract
We propose and study photonic crystal waveguides with bending angles smaller than 90°. The waveguide is formed by coupled defect cavities. To achieve a reflectionless transmission through an acute angle, we surround the defects in the bends with distorted cells having a prescribed symmetry. Detailed analysis and numerical simulation confirm that the transmission through the acute bend can be increased by two orders of magnitude to 100%.
