Abstract: An optical modulator that utilizes Bloch surface plasmon (BSP) effects is disclosed. The BSP optical (BSPO) modulator (10) includes a permittivity-modulated (P-M) grating (20) that can be one-dimensional or two-dimensional. Electro-optic (EO) substrates (30) sandwich the P-M grating. The EO substrates have electrodes (64) arranged thereon, and a voltage source (60) connected to the electrodes is used to provide an applied voltage (V30) via a modulation voltage signals (SM) that switches the modulator. Index-matching layers (40) may be used to mitigate adverse reflection effects. The BSPO modulator allows for normally incident input light (100I) to be modulated directly without having to generate oblique angles of incidence for the input light in order to excite the surface plasmon.

Abstract: Microstructured optical fiber for single-moded transmission of optical signals, the optical fiber including a core region and a cladding region, the cladding region including an annular hole-containing region that contains non-periodically disposed holes. The annular hole containing region is doped with at least one dopant selected from fluorine and chlorine. The optical fiber provides low bend loss as well as low heat-induced splice loss.

Abstract: This is invention comprises a method an apparatus for Infinite Network Packet Capture System (INPCS). The INPCS is a high performance data capture recorder capable of capturing and archiving all network traffic present on a single network or multiple networks. This device can be attached to Ethernet networks via copper or SX fiber via either a SPAN port (101) router configuration or via an optical splitter (102). By this method, multiple sources or network traffic including gigabit Ethernet switches (102) may provide parallelized data feeds to the capture appliance (104), effectively increasing collective data capture capacity. Multiple captured streams are merged into a consolidated time indexed capture stream to support asymmetrically routed network traffic as well as other merged streams for external consumption.

Abstract: The invention disclosed relates to an improved solvent extraction/soil remediation process for the concurrent removal of hydrocarbon contaminants, and fixation of heavy metals.

Abstract: A process for producing substantially colorless poly(vinyl bromide) homopolymer and copolymer latexes at high rates and in high yields which includes adding an aqueous solution of a reducing agent to an emulsion of vinyl bromide containing a water-soluble peroxide, or adding an aqueous solution of peroxide to an emulsion of vinyl bromide containing a water-soluble reducing agent. The latexes can be dried without significant color development and the poly(vinyl bromide) homopolymers and copolymers obtained therefrom have improved color stability.
