Embodiments described herein generally relate to a wave guide and a method of creating a wave guide. In one embodiment, a method of forming a wave guide is disclosed herein. An inverse master substrate having a plurality of projections extending therefrom is formed. A high refractive index material is formed on a top surface of the inverse master substrate. A glass layer is positioned on a top surface of the high refractive index material. The inverse master substrate is removed from the high refractive index material.
