Claim Text:
1. A scanning projector comprising: a first light source that provides a first light signal characterized by a first wavelength; a second light source that provides a second light signal characterized by a second wavelength; a beam combiner comprising a planar lightwave circuit including plurality of waveguides that are arranged to define a first input port, a second input port, a mixing region, and an output port, the beam combiner: (1) receiving the first light signal at the first input port, (2) receiving the second light signal at the second input port, (3) combining the first light signal and the second light signal into a composite output signal, and (4) providing the composite output signal at the output port; and a scanner, the scanner receiving the composite output signal from the beam combiner and scanning the composite output signal over each of a plurality of image points in a first region.
