Optical interconnects hold the promise of revolutionizing computing speed having higher bandwidth and lower power consumption. For high packing density of optical interconnects, crosstalk is calculated considering the coupling of fields of two parallel identical neighboring waveguides. The study shows that there exists minimum pitch for a particular length and width of the interconnects to avoid significant amount of crosstalk. Again, an optimum ratio of width-to-pitch exists for which crosstalk is minimum.
