A '''waveguide''' is a piece of transparent material where an image can be shone in one part and exit another part that is separate. It is useful in making display glasses that use optical see through displays.

A waveguide often serves as a [[combiner]].

Waveguides are often based on [[diffraction grating]]s. A [[diffractive waveguide]] is a piece of glass or plastic with diffraction gratings on it.

A pupil-expanding waveguide was used in the [[Magic Leap 1]].

==Manufacturing==
Waveguides can be built in layers.

Waveguides can be made using lithography.<ref name="o061">{{cite web | title=A Better Way for Manufacturing Diffractive Optics on AR Waveguides | website=YouTube | date=2024-03-06 | url=https://www.youtube.com/watch?v=7XOj-6YUCCI | access-date=2024-08-30}}</ref>
