Multimode polymeric Y junctions for star couplers in backplane optical interconnect.
Three different multimode polymeric Y junctions with 50:50 splitting ratios were designed and their performance analyzed with ray tracing and measurements. There is agreement between measurements and modeling. The best performance is found for a Y junction in which the waveguide is split to S bends with 50% widths.
