Abstract:
A waveguide structure adapted for use in an optoelectronic receiver comprising:a substrate connected to the optoelectronic receiver; and an interface for coupling the optoelectronic receiver to a demultiplexing device, the interface comprising, a first ground structure embedded in the substrate; a first signal line embedded in the substrate and positioned adjacent and substantially parallel to the first ground structure; a second ground structure embedded in the substrate, having a first separation distance from the first ground structure, positioned adjacent and substantially parallel to the first signal line, wherein the first signal line is positioned between both the first and second ground structures; a second signal line embedded in the substrate, having a second separation distance from the first signal line, positioned adjacent and substantially parallel to the second ground structure, wherein the second ground structure is positioned between both the first and second signal lines; and a third ground structure embedded in the substrate, having a third separation distance from the second ground structure, positioned adjacent and substantially parallel to the second signal line, wherein the second signal line is positioned between both the second and third ground structures.
