New Optical Splitter Design for Network Scalability and Flexibility

摘要

In this paper, we present the design of two optical splitter which are 2x3 optical splitter-combine and Multi Ratio Optical Splitter (MROS) based on waveguide with SU-8 polymer material. The technology ensures low cost fabrication and excellent performance as compared to conventional technique that uses fused coupler for optical splitter fabrication. Both optical splitter-combine and MROS are suggested to be used in passive customer access network FTTH-PON. The optical splitter-combine is used to variety the signals send to the premises and as for MROS, it is used in power management in minimizing the power loss. The problems arose such as the loss of output power is also discussed. The simulation result shows that factor such as wide-angle branching and refractive index will increase the output power loss. To obtain maximum power, the optimization of those parameters’ value must be used. This designed optical splitter is operated at wavelength 1500 nm – 1600 nm. In this study, we characterized the trend of total output power with the effect of the parameters studied.
