Previous theory of intersecting waveguides (optical) based on the idea of composite modes is unable to explain a variety of important experimental observations. We have developed a systematic theory which is in good agreement with the experiment. In addition, our theory points out the novel physical effects associated with this geometry. It is found that the crosstalk vanishes for an intersection angle which is twice the angle of rays in the individual waveguides. A sharply peaked radiation pattern from the intersection region of the two waveguides is both predicted and observed for the first time.
