A novel compact polymeric multimode power splitter was designed and fabricated, with its overall length 30% shorter than the conventional Y-junction splitter. Using the simulation software BeamProp, we have done selective analysis to determine the parameters of the splitter. By using soft-lithography the 1×8 polymeric power splitters were prototyped and the measurement was in a good agreement with the calculated result. This splitter caters for the trend of micromation of the optical communication devices and the technology used features unique advantages of fast-easy producing, low-cost fabrication and possible mass-production.
