Longitudinally shifting waveguide junctions can achieve high efficiency light coupling from external silica waveguides into photonic crystal waveguides (PCWs) without requiring taper PCW structures in the waveguide junctions. Due to the periodic field distribution of PCWs along the propagation direc
## Abstract Different taperedβwaveguide junctions are investigated for coupling light between traditional dielectric and photonicβcrystal waveguides characterized by a triangular lattice of air holes. Efficient approaches for the taper design, which allow flatβtransmission efficiency higher than 85
