摘要：
A new technique for the reduction of the optical power loss at the branching point of the rib waveguide Y-branch power splitter on silicon substrate has been proposed. The rib height of the waveguide nearby the branching point is increased which causes the decrease in the effective index of the region lying between the two output branches nearby the branching point. The beam propagation method is applied for the analysis of the rib waveguide Y-branch optical power splitter. It is inferred from this analysis that the value of the power loss can be reduced by similar to 50% by decreasing the effective index. (C) 2001 published by Elsevier Science B.V.
