Abstract
A scanning projector suitable for projecting an image comprising a plurality of light signals of different wavelengths is disclosed. Embodiments of the present invention comprise a beam combiner comprising a planar lightwave circuit that includes a plurality of surface waveguides arranged in define a plurality of input ports, a mixing region, and an output port. Each input port receives a different light signal and provides it to the mixing region. The mixing region combines the plurality of into a single composite output beam that is scanned over a region to create an image in a region.
