Spot-size converter
A tapered waveguide structure that expands the tightly confined mode of a submicron chip waveguide to match the much larger mode of an optical fibre or a III-V laser.

Notes
Mode mismatch is the single biggest loss term at a chip facet, so the converter design sets coupling efficiency.
