1. A display device, comprising:
a display;
a light emitter configured to emit both a non-visible light and a visible light;
an optical waveguide directly coupled to the light emitter by a single optical coupler and configured to receive and communicate both the non-visible light and the visible light, wherein the visible light is configured to be coupled to the display; and
an optical device coupled to the optical waveguide and configured to receive the non-visible light and direct a non-visible light beam to a user's eye.
