Abstract
The Y branch is the fundamental structure in the planar lightwave circuit
and the property of its output is analyzed in this paper. The symmetry of Y branch’s output is optimized by optimizing the length of the tapered waveguide in Y branch and by inserting a straight waveguide with proper length between the tapered waveguide and the input waveguide.
