Waveguide with anti-reflection properties

A head-mounted display (HMD) system comprising:

• a lens element supported by a support structure, the lens element including a waveguide, the waveguide comprising:
• an incoupler;
• an outcoupler;
• an exit pupil expander;
• and
• an anti-reflection coating selectively disposed in an area between the exit pupil expander and the outcoupler, wherein the exit pupil expander and the outcoupler are substantially free from the anti-reflection coating.

A method comprising:

• disposing an incoupler within a first area of a waveguide;
• disposing an outcoupler within a second area of the waveguide;
• disposing an exit pupil expander within a third area of the waveguide;
• and
• disposing an anti-reflection coating within a fourth area of the waveguide different than the first, second, and third areas of the waveguide, wherein the first area, the second area, and the third area are substantially free of the anti-reflection coating.
