Abstract:
A waveguide mode expander couples a smaller optical mode in a semiconductor waveguide to a larger optical mode in an optical fiber. The waveguide mode expander comprises a shoulder and a ridge. In some embodiments, the ridge of the waveguide mode expander has a plurality of stages, the plurality of stages having different widths at a given cross section.

Claim (Index 9):
The method of  claim 7 , wherein propagating the optical beam into the input end comprises coupling the optical beam through an angled interface between the shoulder portion and the waveguide, wherein the angled interface forms a plane that is not orthogonal with respect to a propagation direction of the optical beam.
