    摘要: This disclosure is directed to thermally controlled optical systems. In one aspect, an optical system includes a sub-wavelength grating having a planar geometry and a grating pattern associated with a particular shape of, and direction in which, a wavefront emerges from the grating, when the grating is illuminated by a beam of light. The system includes at least one heating element separately connected to a current source. The current source to inject a current into each heating element to heat a corresponding region of the grating and produce a desired change in the shape of, and/or direction in which, the wavefront emerges from the grating.

    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: 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.

    摘要: Embodiments of the present invention relate to planar optical devices composed of one or more sub-wavelength diffraction grating layers. In one embodiment, an optical device includes a first substantially planar reflective structure (104,1904), a second substantially planar reflective structure (106,1906), and a substantially planar sub-wavelength grating layer (102,1902) disposed between the first reflective structure and the second reflective structure. The grating layer is configured with lines (208-211,214-217) having line widths, line thicknesses, and line period spacing selected to control phase changes in different portions of a beam of light transmitted through the optical device.
