High Coupling Efficiency Etched Facet Tapers in Silicon Waveguides

High Coupling Efficiency Etched Facet Tapers in Silicon Waveguides

We demonstrate a platform based on etched facet silicon inverse tapers for waveguide-lensed fiber coupling with a loss as low as 0.7 dB/facet. This platform can be fabricated on a wafer scale enabling mass-production of silicon photonic devices with broadband, high-efficiency couplers.
