Abstract
This paper presents a general theoretical investigation of the crossing waveguide structures constructed by large-size single-mode rib semiconductor waveguides. The theoretical model is based on beam propagation method and effective index method. The propagation characteristics of three kinds of structure are analyzed and compared. The numerical result show that these structures exhibit similar characteristics at large crossing angles but divergences exist at small crossing angles. It is found that mode-interference doesn't exist in y-junction.
