Customizing the refractive index of a surface

Mechanisms for customizing a refractive index of an optical component are disclosed. In one example, sub-wavelength openings are formed in a top layer of anti-reflective (AR) material of an optical component to tailor transmission characteristics of the AR material over a range of angles of incidenc...

Summary:Mechanisms for customizing a refractive index of an optical component are disclosed. In one example, sub-wavelength openings are formed in a top layer of anti-reflective (AR) material of an optical component to tailor transmission characteristics of the AR material over a range of angles of incidence and a range of wavelengths. In another example, sub-wavelength openings are formed at different filling fractions in the surface of the optical component.
