This research presents a novel strategy for enhancing optical network efficiency by implementing taper-based single-mode step-index (SI) core polymer Y-branch multimode interference (MMI) splitter. The innovative splitter design offers notable benefits in terms of performance, cost-effectiveness, and scalability. By capitalizing on the inherent attributes material, including its minimal propagation losses flexibility, we meticulously engineer this Y-Branch MMI A 5 μm width is purposefully maintained input output components to uphold conditions. Embracing self-imaging principle, optimization are conducted employing beam method at 1.55 wavelength. SI splitters achieve commendable power splitting 86%. Our examination shows an excess loss 0.52 dB 0.50 TE TM modes, respectively. Furthermore, calculated polarization dependence (PDL) 0.015 dB, with only 0.00019 dB/μm.
