    摘要： An optical coupling system and method of fabrication are included. The optical coupling system includes a substrate layer and an optical waveguide material overlying the substrate layer. The optical waveguide material can include a grating. The system also includes a cover material overlying the optical waveguide material to couple an optical signal to the optical waveguide material via the grating at a coupling angle. Approximately zero energy of the coupled optical signal is lost in the substrate layer due to a combination of the coupling angle and a difference in refractive indices between the cover material and the substrate layer.

    摘要： Planar, polarization insensitive, optical elements to control refraction of transmitted light in free space are disclosed. In one aspect, an optical element includes a substrate having a planar surface, and a polarization insensitive, high contrast, sub-wavelength grating composed of posts that extend from the planar surface. The grating has at least one region. Within each region, cross-sectional dimensions of the posts and/or lattice arrangement of the posts are nonperiodically varied to control refraction of light transmitted through the optical element.
