Abstract
An image projection system having a laser projector that projects two differently polarized images on a display region is disclosed. The laser projector enables viewing the two differently polarized images as a three-dimensional image. The image projection system includes a planar lightwave circuit-based beam combiner that enables multiple colors of laser light having different polarization modes to be combined in a single output beam that is scanned over the display region at video rates to produce the two polarized images.
