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： Light-detection systems that do not destroy the light to be detected or change the propagation direction of the light are described. In one aspect, a light-detection system includes an optical element composed of a substrate with a planar surface and a polarization insensitive, high contrast, sub-wavelength grating composed of posts that extend from the planar surface. The posts and/or lattice arrangement of the posts are non-periodically varied to impart orbital angular momentum and at least one helical wavefront on the light transmitted through the optical element.

摘要： An optical connector includes a first optical fiber and a second optical fiber. A first planar lens is positioned to operate on light exiting the first optical fiber to create a predetermined change in a wave front of the light. A second planar lens is positioned to accept the light from the first planar lens, the second planar lens focusing the light onto the second optical fiber. The first planar lens and second planar lens each include a regularly spaced array of posts with periodically varying diameters.
