摘要:
A beam combiner is disclosed that comprises a planar lightwave circuit that is based on undoped silicon nitride-based surface waveguides, wherein the planar lightwave circuit comprises a plurality of input ports, a mixing region, and an output port, and wherein the mixing region comprises a plurality of directional couplers that are arranged in a tree structure. Embodiments of the present invention are capable of combining a plurality of light signals characterized by disparate wavelengths on irregular spacings with low loss. Further, the present invention enables high-volume, low cost production of beam combiners capable of combining three or more light signals into a single composite output beam.
