Optical splitters are promising photonic devices for next-generation integrated circuits, which enable signal distribution and routing between the different components, facilitating complex optical functionalities on a single chip. This research introduces what we believe is novel numerical technique enhancing network efficiency by incorporating taper-based step-index (SI) Y-branch multimode interference (MMI) splitter with organic-inorganic hybrid polymer materials. The proposed device comprises core width of 5 µm input output waveguides to satisfy single-mode conditions. We designed optimized MMI using beam propagation method (BPM). demonstrates power splitting property an 86%. excess losses 0.52 dB 0.50 TE TM modes, respectively, at 1.55 µm. polarization dependence loss (PDL) (PL) 0.015 0.00019 dB/µm, respectively.
