| 20100014808 | Hybrid dielectric/surface plasmon polariton waveguide with grating coupling - The present invention provides a hybrid dielectric/SPP waveguide that can form either a single mode, single polarization waveguide, or a multi-mode waveguide. When multi-mode, this invention effectively transfers energy back and forth between the dielectric waveguide and metal surface. This improves on standard SPP modes, yielding longer range propagation along with high intensity near the metal surface at decisive locations. When single-mode, this hybrid waveguide allows for control of propagation and confinement for applications such as telecommunications optics integrated on silicon microchips. Gratings may be patterned in the metal for coupling light into and out of the modes or for use as mirrors in the mode. For areas where very long ranges are required, a metal grating may be used to couple light into the mode, but then the metal may be removed in other regions and make the range of the mode virtually infinite (limited by surface roughness). | 01-21-2010 |

| 20090052827 | Silicon-Compatible Surface Plasmon Optical Elements - This invention provides fundamental science and novel device architectures for surface plasmon (SP)-based, complementary metal oxide semiconductor (CMOS)-compatible, optical elements such as modulators, couplers, and switches. The primary focus of the work is on waveguides based on an ultra-long-range surface plasmon (ULRSP) waveguide mode recently discovered by our team. This mode exists at the metal-dielectric interfaces in a silicon-oxide-metal-silicon layer structure. While initial work focuses on noble metals to support the ULRSP, our analysis shows Si processing-compatible metals such as Cu and Al can also be used. Our modeling has also shown that variation in the thickness of the oxide layer can be used to give unprecedented propagation lengths in such structures. Electrically-induced free carrier modulation of the dielectric constant in the Si adjacent to the oxide can modulate the waveguide properties allowing novel Si-compatible electro-optic devices to be created. These waveguides function as the “wiring” in new classes of optical chips. This invention also provides integration of ULRSP waveguides and switches with other optical elements to create entirely new classes of hybrid optoelectronic technologies for defense applications. These range from chip-based chemical agent detection to extremely high performance processors and even all-optical computations. | 02-26-2009 |

During field or other operations, sensors may take vibrational readings along the pipe when an operational fluid (e.g., drilling fluid) flows through the pipe. The operational vibrations may be analyzed via cross-correlation and/or deconvolution to separate the operational combined structural response of the fluid filled pipe from excitation and base coupling effects. The baseline and operational structural responses may compared. Similarities or differences in the structural responses may be used to determine fluid properties of the operational fluid. | 10-09-2008 |
