A conventional SOI-based optical power splitter has been built where absorptance and transmittance were studied against radius, from which an optimized radius of 20 um was attained, after which the parameters become saturated. Optical power splitters and combiners are crucial in broadband optical communication, suppressing active devices in passive optical networks. They enable Photonic Integrated Circuits (PICs) by creating specific photonic band gaps. They are easy to fabricate and have low sensitivity to tolerances. Performance is evaluated based on transmittance and absorptance. This paper aims mainly at the radius optimization for the 1x2 power splitter. Apart from CMT, FEM analysis is used to study the losses in conventional splitters based on rectangular silicon-on-insulator (SoI) waveguide structures.
