The Design Of 2x3 Optical Splitter-Combine Based On Primary Planar Waveguide

In this paper, we present the design of 2x3 optical splitter-combine based on waveguide with SU-8 polymermaterial. The technology ensures low cost fabrication and excellent performance as compared to conventionaltechnique that uses fused coupler for optical splitter fabrication. The optical splitter-combine is suggestedto be used in passive customer access network FTTH-PON to variety the signals send to the premises. It isthe first time reported. The problems arose such as the loss of output power is also discussed. The simulationresult shows that various factors; namely the width of waveguide, refractive index and wide-angle branchingwill increase the output power loss. To obtain maximum power, the optimization of those parameters’ valuemust 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.
