Abstract: In this study the level of sidewall roughness was monitored with depth and structure of roughness to see its effect to signal quality of optical network. Sidewall roughness is contributes to scattering loss in waveguide and leads to signal distortion. Y-shaped waveguide to develop 1×2 optical splitter was designed with 6 different roughness depth and roughness was placed at 3 different structures. 1×2 optical splitter waveguide integrated into optical network and the signal quality analyzed by its Q-factor. Simulation results show that Q-factor values was decreasing as roughness get deeper on 0.6 μm and sidewall roughness on s-bend structure also, contributes to higher signal distortion compares to roughness on linear structure. Therefore, it is necessary for us to monitor the level of sidewall roughness to ensure the quality of optical signal.
