中文摘要	we propose an approach to construct waveguide intersections with broad bandwidth and low cross-talk for square-lattice photonic crystals. by utilizing a vanishing overlap of the propagation modes in the waveguides created by defects which support dipole-like defect modes. the finite-difference time-domain method is used to simulate the waveguide intersection created in the two-dimensional square-lattice photonic crystals. over a bandwidth of 30 nm with the center wavelength at 1300 nm, transmission efficiency above 90% is obtained with cross-talk below -30 db. especially, we demonstrate the transmission of a 500-fs pulse at 1.3 am through the intersection, and the pulse after transmission shows very little distortion while the cross-talk remains at low level meantime.
