ABSTRACT
We theoretically and experimentally investigated compact Y-splitter and aperture-assisted coupler based on subwavelength plasmonic slot waveguides to demonstrate their capabilities for routing light at the nanoscale. The devices were fabricated on a silicon-on-insulator platform and integrated with conventional silicon photonic waveguides which enables efficient light coupling into the nanoscale plasmonic slot channels. The fabricated splitter and coupler structures exhibited wideband operation over the 1510–1630 nm telecommunication wavelength range, making them suitable for use as basic building blocks for light manipulation below the diffraction limit in plasmonic slot waveguides.
