摘要： Embodiments of the present invention are directed to optical waveguide-to-fiber interconnects. In one aspect, an optical fiber-to-waveguide interconnect includes a grating coupler (102) located at the end of a waveguide, and a grating layer (110) disposed on the end of an optical fiber (112). The optical fiber includes a core (118) and the grating layer includes a planar, non-periodic, sub-wavelength grating (116). Light carried by the waveguide into the grating coupler is output and coupled into the core via the sub-wavelength grating, and light transmitted along the core to the grating layer is directed by the sub-wavelength grating into the grating coupler for transmission in the waveguide.

摘要： Embodiments of the present invention are directed to nanowire-based systems for performing surface-enhanced Raman spectroscopy. In one embodiment, a system comprises a substrate (102) having a surface and a plurality of tapered nanowires (104) disposed on the surface. Each nanowire has a tapered end directed away from the surface. The system also includes a plurality of nanoparticles (110) disposed near the tapered end of each nanowire. When each nanowire is illuminated with light of a pump wavelength, Raman excitation light is emitted from the tapered end of the nanowire to interact with the nanoparticles and produce enhanced Raman scattered light from molecules located in close proximity to the nanoparticles.

摘要： A backlight includes a plate light guide to guide light, a light source to produce light, and a collimating reflector to substantially collimate the produced light. The collimating reflector also is to direct that collimated light into the plate light guide as guided light of the plate light guide. A portion of the guided light in the backlight is to be emitted from a surface of the backlight as emitted light.

摘要： Aspects of the present invention are directed to flat sub-wavelength dielectric gratings that can be configured to operate as mirrors and other optical devices. In one aspect, a grating layer (102) has a planar geometry and is configured with lines (206,207). The lines widths, line thicknesses and line period spacings (208) are selected to control phase changes in different portions of a beam of light reflected from the grating such that the phase changes collectively produce a desired wavefront shape in the beam of light reflected from the grating.

摘要： A direction sensor (200) includes sensor cells (215) that respectively correspond to different directions. Each of the sensor cells (215) includes a light sensor (130, 140) and a grating (120) that couples incident light into the light sensor (130, 140) when the incident light has a specific wavelength and is incident on the grating (120) along the direction corresponding to the sensor cell (215).
