Abstract
In this paper, we propose a new evaluation concept for characterizing multimode optical branching waveguides. We introduce a ray tracing technique to simulate multimode branching waveguides and a phase space expression with the ray position and slope to describe the modal distribution of output light. We have used this technique for branching waveguides, which have a parabolic distributed-index and clarified branching characteristics. Experimental results obtained for diffused branching waveguides are compared to calculation.
