Abstract
Techniques for an optical waveguide with homogenous light intensity output are described herein. In an example, an optical waveguide system includes an optical waveguide substrate and a first holographic layer coupled to the optical waveguide substrate and configured to inject light into the optical waveguide substrate as injected light. The optical waveguide system also includes a second holographic layer coupled to the optical waveguide substrate and configured to receive the injected light and output the injected light as output lights in a direction. The second holographic layer is characterized by a varying diffraction efficiency and the output lights have a homogenous intensity at a distance from the second holographic layer.
