    "abstract": "We study coupling and decoupling of parallel waveguides in two-dimensional\nsquare-lattice photonic crystals. We show that the waveguide coupling is\nprohibited at some wavelengths when there is an odd number of rows between the\nwaveguides. In contrast, decoupling does not take place when there is even\nnumber of rows between the waveguides. Decoupling can be used to avoid cross\ntalk between adjacent waveguides.",
