High-Efficiency Broadband Grating Couplers for Silicon Hybrid Plasmonic Waveguides

High-Efficiency Broadband Grating Couplers for Silicon Hybrid Plasmonic Waveguides

We report the designs of on-chip grating couplers for the silicon hybrid plasmonic waveguides, which is the first proposal, to the best of our knowledge, for the direct coupling between a standard single-mode fiber and a hybrid plasmonic waveguide. By leveraging the apodized gratings and a two-stage...
