摘要： Methods and related apparatuses and mixtures are described for spectroscopic detection of hydrogen sulfide in a fluid, for example a formation fluid downhole. A reagent mixture is combined with the fluid. The reagent mixture includes metal ions for reacting with hydrogen sulfide forming a metal sulfide, and a capping agent that limits growth of the insoluble metal sulfide species by electrosteric or steric stabilization. The particle growth is one of chemical reaction or significant aggregation, and the capping agent further functionalizes the reagent mixture to exhibit properties outside the natural characteristics of the metal sulfide species to allow for spectroscopic detection of the metal sulfide species. The combined mixture and fluid is then spectroscopically interrogated to detect the presence of the metal sulfide thereby indicating the presence of hydrogen sulfide in the fluid. The mixture also includes chelating ligands for sustaining thermal endurance of the mixture under downhole conditions.

摘要： A linearized thermal and optical model of an optical integrated circuit can be used to temperature-stabilize one or more optical elements of the circuit using active temperature regulation. To stabilize a single optical element, such as an arrayed waveguide grating (AWG), a temperature sensor and a heater can be provided proximate to the grating. Thermal and optical coefficients can be then used to select an appropriate temperature set-point for the temperature controller that receives readings from the sensor and determines the power dissipated in the heater. Multiple AWG's can be stabilized individually, using the same process and lumping cross-heating factors together with other environmental factors. Alternatively, multiple AWG's can be stabilized using fewer sensors than AWG's, by stabilizing one of the AWG's in the same manner as in the case of a single AWG, and determining power dissipated in the heaters of the remaining AWG's based on the linearized model.

摘要： An optical integrated circuit (OIC) or optical apparatus upon which a waveguide-grating router (WGR) device is fashioned is provided, where the circuit is configured to optimize a passband for each channel transmitted on an output waveguide. The WGR has two or more waveguides of varying widths optically coupled to a slab waveguide. The widths can be configured to facilitate producing a substantially uniform frequency-limited bandwidth, a substantially uniform wavelength-limited bandwidth, a substantially uniform isolation value, and/or a substantially uniform value for insertion loss between the output waveguides, which in turn facilitates producing optical data communication devices with more consistent transmission parameters and higher quality. In addition to various widths, the shape of the delivering end of a slab waveguide can be fashioned to further improve the consistency and quality of such parameters.
