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 14):
A waveguide mode expander comprising:\n a shoulder portion, comprising non-crystalline silicon, disposed atop a lower cladding layer having a lower index of refraction than the non-crystalline silicon; and a ridge portion, comprising non-crystalline silicon, disposed atop the shoulder portion; and an upper cladding layer, having a lower index of refraction than the non-crystalline silicon, and disposed atop the ridge portion and the shoulder portion; wherein: the shoulder portion and the ridge portion are configured to guide an optical beam from an input end to an output end of the waveguide mode expander; and at least the ridge portion increases in width from an input end to an output end of the waveguide mode expander so as to expand an optical mode of the optical beam as the optical beam propagates from the input end to the output end.
