Abstract
Color-selective waveguides, methods for fabricating color-selective waveguides, and augmented reality (AR)/mixed reality (MR) applications including color-selective waveguides are described. The color-selective waveguides can advantageously reduce or block stray light entering a waveguide (e.g., red, green, or blue waveguide), thereby reducing or eliminating back-reflection or back-scattering into the eyepiece.
Claims20
1-20. (canceled)
An optical device comprising:
- a waveguide comprising one or more patterned regions and one or more unpatterned regions, wherein the one or more patterned regions comprise an incoupling grating (ICG) configured to incouple light of one or more colors into the waveguide;
- and
- a polymer coating forming a surface of the waveguide, wherein the polymer coating includes a chromatic component that is configured to absorb at least 90% of light of one or more wavelength ranges that is traveling through the polymer waveguide and that the incoupling grating is not configured to incouple.
