Abstract

Based on a simplified coherent coupling effect, a compact Y-branch power divider with polymer waveguides is presented. The simulated and measured normalized transmitted powers are 0.88 and 0.75 when the effective branching angle is as large as 19.7/spl deg/. For the same transmission efficiency, both theoretical and experimental results show that the length required for the proposed Y-branch is shorter than those for the conventional S-bend configurations. Furthermore, the transmission spectrum shows that the proposed Y-branch is suitable for a dense wavelength-division-multiplexing application.
