Abstract
Techniques for optical waveguides with multiple layers in a stack arrangement are described herein. In an example, an optical waveguide system includes a waveguide substrate, a first holographic optical element, a second holographic optical element, and an optical de-coupling layer. The first holographic optical element includes a first photopolymer layer and excluding a first polymer substrate and the second holographic optical element includes a second photopolymer layer. The first photopolymer layer is attached to the waveguide substrate and to either the second holographic optical element or the optical de-coupling layer.
