A study was performed on the photonic crystal waveguides (PCW) with multiple 90° bends. It was shown that such waveguides exhibited excellent guiding properties despite the existence of multiple 90° bends. It was estimated that the propagation velocity of the waveguide was about 0.47 c, regardless of the number of bends, and that the bending loss was only 0.1 dB per bend.
