A rigorous modal transmission-line theory (MTLT) based on effective dielectric method (EDM) is introduced and developed to analyze the polarization beam-splitting of optical rib-type directional coupler with three guiding layers. Furthermore, to confirm the validity of approach proposed in this paper, we compare our results with those ones of BeamPROP, which is a commercial software package used widely. Consequently, the numerical results reveal that the hybrid modes incident into a guiding channel of rib-type coupler are split well through upper and lower guiding channels in a polarization length.
