Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 8:
9. A modulator, comprising:
a first waveguide; and
a second waveguide, comprising:
a light input end,
a light output end,
a first semiconductor material,
a second semiconductor material different from the first semiconductor material, the second semiconductor material contacting the first semiconductor material along a boundary area, wherein a first light output of the first waveguide is combined with a second light output from the light output end, 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, wherein the first waveguide and the second waveguide are part of a processor, and

a core and a cladding, wherein the core is part of a folded waveguide phase shifter in which light may propagate through from the light input end to the light output end.
