Abstract: A handheld device (310) includes: a transmitter or receiver (410) of a signal beam (340) for quantum key distribution; and a source (412, 414) of alignment beams (312, 314, 316, 318) that diverge from each other in a pattern that matches sensors (322, 324, 326, 328) on a station (320) containing a receiver or transmitter (430) for the quantum key distribution. The alignment beams from the handheld device (310) are of sufficient intensity to produce on the station visible spots that facilitate manual alignment of the handheld device (310). The station (320) can measure a position and a direction of respective alignment beams and dynamically steer the signal beam (340) according to the measurements.

Abstract: 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.

Abstract: Optical polarizers and optical isolators and systems that incorporate the optical polarizers and isolators are disclosed. In one aspect, an optical isolator includes a Faraday crystal with a first surface and a second surface opposite the first surface, a first one-dimensional sub-wavelength grating disposed on the first surface, and a second one-dimensional sub-wavelength grating disposed on the second surface. The isolator is to receive a first input beam of light on the first grating and output a polarized first output beam of light through the second grating approximately parallel to the first input beam. The isolator is to also receive a second input beam of light on the second grating and output a polarized second output beam of light through the first grating with the second output beam offset from the second input beam.

Abstract: 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.

Abstract: Embodiments of the present invention are directed to systems for performing surface-enhanced Raman spectroscopy. In one embodiment, a system (100, 400, 600, 800, 900, 950) for performing Raman spectroscopy comprises a substrate (102) substantially transparent to a range of wavelengths of electromagnetic radiation and a plurality of nanowires (104, 602) disposed on a surface of the substrate. The nanowires are substantially transparent to the range of wavelengths of electromagnetic radiation. The system includes a material disposed on each of the nanowires. The electromagnetic radiation is transmitted within the substrate, into the nanowires, and emitted from the ends of the nanowires to produce enhanced Raman scattered light from molecules located on or in proximity to the material.
