    "abstract": "Low crosstalk intersections formed by two crossing coupled cavity waveguides\n(CCWs), which are formed by series of \\textit{mono-mode} cavities in a two\ndimensional photonic crystal structure, are investigated. Although the\nindividual cavities are \\textit{mono-mode}, the modes of the properly designed\nCCWs (which are called \\textit{supermodes} in this paper) may be dipole-like,\nand antisymmetry along the axis of the other perpendicular CCW, which ensures\nthe low crosstalk of the intersections. According to the results of coupled\nmode analysis, we divide the intersections into two kinds based on the number\nof cavities of each CCW, and the transmission and crosstalk spectra of both\nkinds are numerically obtained using finite difference time domain (FDTD)\nmethod. The results show that crosstalk power is lower than -30dB. We also\ndiscuss the factors that affect the performance of the intersections.",
