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.

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： In accordance with an aspect of the invention, a system has a transmitter and a receiver, where the transmitter includes a beam source and an optical element. The beam source produces a beam that represents information, and the optical element alters the beam so that the beam has a uniform intensity over a cross-sectional area. The receiver is separated from the transmitter by free space through which the beam propagates and includes an active area positioned to receive a portion of the beam that the receiver converts into a received signal. To accommodate possible misalignment, the cross-sectional area of the beam is larger than the active area by an amount that accommodates a range of misalignment of the receiver with the transmitter.
