Abstract

An optical waveguide combiner includes an optical waveguide substrate and an optical input region. The optical input region includes an optical input diffractive grating integrated in, or disposed on, the optical waveguide substrate. An optical output region includes an optical output diffractive grating integrated in, or disposed on, the optical waveguide substrate, At least one non-diffractive region includes at least one optical non-diffractive array of nanostructures, wherein said at least one optical non- diffractive array of nanostructures is integrated in, or disposed on, the object side of said optical waveguide substrate and at least partially surrounds at least said optical output grating; wherein the external visible reflectance of said at least one non- diffractive array of nanostructures is substantially equal to the external visible reflectance of said optical output grating.
