Polarization Splitter Using Hybrid Dielectric Surface Plasmonic Waveguide

As integrated photonic devices continue to move to small waveguide dimension, polarization-dependent dispersion and loss take on greater significance that are not desirable. This paper describes the design, development and demonstration of a novel polarization splitter based on plasmonic waveguides. The splitter is fabricated on silicon-on-insulator platform using standard CMOS technology. The splitter is capable of achieving >15 dB extinction ratio with <0.5 dB insertion loss. Measuring at just 6.5 um, the splitter is ideal for densely integrated photonic circuits.
