Claim 13:
14. A method, comprising:
connecting a first waveguide with a second waveguide different than the first waveguide, wherein the second waveguide comprises:
a light input end,
a light output end,
a first semiconductor material, and
a second semiconductor material, different from the first semiconductor material, the second semiconductor material contacting the first semiconductor material along a boundary area, wherein the boundary area forms a plurality of discrete multi-pointed enclosed shapes when viewed from a longitudinal cross sectional view extending from the light input end to the light output end, and wherein the first waveguide and the second waveguide are part of a processor; and

combining a first light output of the first waveguide with a second light output from the light output end.
