Abstract: An anti-reflective coating including a plurality of first layers, which each comprise a first material with a relatively high refractive index, and a plurality of second layers, which each comprise a second material with a relatively low refractive index. A total thickness of the first layers comprised of the first material is about 120 nm or less. Additionally, the anti-reflective coating is configured to absorb about 0.25% or less of light for a single reflection of the average of the s- and p-polarizations of the light, at every wavelength between about 425 nm to about 495 nm, when the light is propagating under total internal reflection.

Abstract: An optical coupler device for coupling light with a light guide is provided. The device includes a first layer having a plurality of first diffraction gratings spaced apart via first trenches, the first diffraction gratings and the first trenches forming first periodic units. The device also includes a second layer having a plurality of second diffraction gratings spaced apart via second trenches, the second diffraction gratings and the second trenches forming second periodic units. Additionally, the second periodic units are offset in a lateral axis of the optical coupler device relative to the first periodic units by a relative shift distance S2 that is in a range from about 10 nm to about 600 nm.
