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 2):
A method of modifying mode size of an optical beam, comprising:\n propagating the optical beam, with an initial mode size, into an input end of a waveguide mode expander, wherein the waveguide mode expander comprises:\n a shoulder portion, comprising non-crystalline silicon, that is disposed on a substrate and traverses the substrate from the input end to an output end of the waveguide mode expander, and \n a ridge portion, comprising non-crystalline silicon, that is disposed on the shoulder portion; \n propagating the optical beam through the waveguide mode expander, wherein at least the ridge portion changes in width from the input end to the output end, so as to modify the optical beam propagating from the input end to the output end from the initial mode size to a final mode size; and propagating the optical beam, with the final mode size, out of the output end of the waveguide mode expander.
