Abstract
A grating-coupler assembly with a small mode-field diameter for photonic-integrated-circuit systems is disclosed. The assembly includes a silicon waveguide supported by a silicon-on-insulator substrate, and a grating coupler supported by the substrate and optically coupled to the silicon waveguide. The assembly has an optical fiber with a mode-field diameter in the range from 5 μm to 6 μm. One end of the optical fiber is disposed adjacent the grating coupler to define a coupling efficiency of 0.7 or greater.
