Abstract
A device for projecting a virtual- or augmented-reality image may include a waveguide and an in-coupler directing light into the waveguide such that the light is propagated through the waveguide via total internal reflection. The waveguide may include a core, a substrate, and a stack of thin films overlaying a surface of the core. A refractive index of at least one of the thin films of the stack may differ from that of the core. Adjacent thin films may have different refractive indices from one another.
