Ultra‐compact and ultra‐broadband hybrid plasmonic‐photonic vertical coupler with high coupling efficiency, directivity, and polarisation extinction ratio
Abstract An ultra‐compact, ultra‐broadband vertical coupler for dense photonic integrated circuits is reported with a 1.07 × 0.62 μm2 wavelength‐scale footprint. This hybrid plasmonic‐photonic coupler uses a unique two‐plane plasmonic nanoantenna array on a silicon‐on‐insulator waveguide. The in‐ an...
