Ultra-compact and ultra-broadband hybrid plasmonic-photonic vertical coupler with high coupling efficiency, directivity, and polarisation extinction ratio
(2022)
Journal Article
An ultra-compact, ultra-broadband vertical coupler for dense photonic integrated circuits is reported with a 1.07×0.62μm2 wavelength-scale footprint. This hybrid plasmonic-photonic coupler uses a unique two-plane plasmonic nanoantenna array on a sili...
