Abstract
Systems and methods to reduce light loss from a waveguide. The system includes a waveguide having an incoupler to direct light into the waveguide and a laser projector having laser diodes mounted to a substrate. The laser projector is configured to provide a plurality of laser light beams to the incoupler of the waveguide. The system further includes at least one alignment component configured to align the plurality of laser light beams tangent with an edge of the incoupler to minimize light lost from the waveguide through contact with the incoupler more than once.
