Abstract: A device and method for dynamically tuning a long-period grating of an optical fiber is disclosed. The grating is made tunable by using a controlled strain imposed on the fiber adjacent the grating, wherein the strain comprises an electromechanical force, magnetostrictive force, magnetic force, or a thermally-induced force. An improved optical communication system comprising a dynamically gain-equalized amplifier device, a wavelength feedback device, and the tunable long-period grating device is also disclosed. In the communications system, the grating device is reconfigured to have a desired broadband filtering frequency, thus equalizing the amplifier gain, in response to feedback from the wavelength detector.

Abstract: In accordance with the invention, a tunable fiber grating comprises a fiber grating secured to a magnetostrictive body so that magnetostrictive strain will be transmitted to the grating. An electromagnet is disposed adjacent the magnetostrictive body for applying a magnetic field along the body. Control of the current applied to the electromagnet permits control of the strain transmitted to the fiber grating, and thus control of the grating spacing and reflection frequency. In a preferred embodiment the magnetostrictive body is cylinder bonded along the grating. In alternative arrangements, the magnetostrictive effect can be mechanically amplified. An add/drop multiplexer employing the tunable gratings is described.

Abstract: The invention is embodied in a soft magnetic thin film article comprising an iron-chromium-nitrogen (Fe--Cr--N) based alloy and methods for making such article. The soft magnetic thin film article is formed using an iron-chromium-nitrogen based alloy with tantalum in one embodiment and with at least one of the elements titanium (Ti), zirconium (Zr), hafnium (Hf), vanadium (V), molybdenum (Mo), niobium (Nb) or tungsten (W) in another embodiment. The article is formed such that the alloy has a relatively high saturation magnetization (e.g., greater than approximately 15 kG) and a relatively low coercivity (e.g., less than approximately 2.0 oersteds) in an as-deposited condition or, alternatively, with a very low temperature treatment (e.g., below approximately 150.degree. C). The inventive films are suitable for use in electromagnetic devices, for example, in microtransformer cores, inductor cores and in magnetic read-write heads.

Abstract: A high-strength Pb-free solder alloy, based on the Sn--Ag--Zn system, is disclosed. The Pb-free solder alloy contains, in weight percent, 0.2-0.6% Zn, 1-6% Ag, one or both 0.2-0.6% In and 0.2-0.6% Bi, and the balance Sn. The addition of Zn significantly improves the mechanical strength and creep resistance of e.g., Sn--3.5% Ag eutectic solder while maintaining substantially the same level of ductility. The increase in strength is as much as 48% over that of the Sn--3.5% Ag alloy. This strengthening from the Zn additions is attributed to a uniform solidification structure and a substantial refinement of the precipitates in the alloy. Essentially all of the added Zn resides in the more corrosion-resistant, Ag-based, intermetallic precipitates, leaving the Sn-rich matrix primarily free of Zn in solid solution.

Abstract: This application describes a new method for rapid thinning, planarizing and fine polishing surfaces of diamond to the submicron/nanometer level so that large area, uniform thickness diamond wafers can be obtained. The method combines both chemical (dissolution of carbon in molten metals) and mechanical (rotating or moving sample fixtures in contact with the dissolving metals) polishing to achieve flat, smooth surface finishes in a relatively short period of time, thus improving the quality and economics of the overall polishing process. Several embodiments of apparatus for performing such chemical-mechanical polishing (CMP) of diamond are described.

Abstract: The present invention provides improved methods for making field emission devices by which one can pre-deposit and bond the diamond particles or islands on a flexible metal foil at a desirably high temperature (e.g., near 900.degree. C. or higher), and then subsequently attach the high-quality- emitter-coated conductor foil onto the glass substrate. In addition to maximizing the field emitter properties, these methods provide high-speed, low-cost manufacturing. Since the field emitters can be pre-deposited on the metal foil in the form of long continuous sheet wound as a roll, the cathode assembly can be made by a high-speed, automated bonding process without having to subject each of the emitter-coated glass substrates to plasma heat treatment in a vacuum chamber.
