    摘要： A solder composition that bonds well to oxides and other surfaces to which solder bonding is conventionally difficult is provided. The solder is particularly useful for reliable bonding and packaging of optical components that often have oxide surfaces. The solder composition exhibits a microstructure containing a solder matrix in which is distributed fine, micron-scale islands of rare-earth-containing intermetallic particles. The existence of the islands makes the rare earth elements better available for bonding, and reduce the extent to which the rare earths are oxidized. Advantageously, the solder contains Au and/or Ag, in which the rare earth elements tend to have some solid solubility. Due to this solubility, the Au and/or Ag tend to provide some additional protection of the rare earths against oxidation, and thereby also provide accelerated dissolution of the rare earth into the molten solder.

    摘要： The invention provides an article comprising a solder that bonds well to oxides and other surfaces to which solder bonding is problematic. The solder composition contains one or more rare earth elements, which react with the oxide or other surface to promote bonding, and further contains sufficient Au and/or Ag to act as carriers for the rare earths. Because rare earths have some solid solubility in Au and Ag, the problem of intermetallic formation is lessened or eliminated, and improved bonding to oxide surfaces is attained.

    摘要： An actuation device employing square-loop latchable magnetic material having a magnetization direction (polarization) capable of being changed in response to exposure to an external magnetic field is disclosed. The magnetic field is created by a conductor assembly with non-solenoid configuration. Once the magnetization direction of the material is so changed, the external magnetic field is no longer required to maintain the new magnetization direction. The latchable magnetic material is disposed on the mobile electrode of a switching device, and another magnetic material is disposed in spaced relation to the latchable magnetic material on a stationary electrode or surface. By applying an electrical current to a conductor assembly arranged proximate the latchable material, a magnetic field is created about the latchable magnetic material, to change the magnetization direction and thereby enable the attraction or repulsion of another magnetic material located on the stationary electrode. The resulting relative displacement of the mobile and stationary electrodes effects the selective connection or disconnection of electrical contacts carried on or associated with the respective electrodes of the actuation device without requiring additional power in order to maintain the switched state of the electrodes.

    摘要： An article comprising an alloy exhibiting high magnetostriction in relatively low applied magnetic fields is provided, the alloy capable of being formed in a relatively easy manner and having desirable physical properties. The Co--Fe alloy of the invention exhibits a magnetostriction of at least 100.times.10.sup.-6 in a magnetic field less than 400 Oe, advantageously in a magnetic field less than 100 Oe. The alloy is formed by plastically deforming the alloy, e.g., by cold rolling, to a reduction in cross-sectional area of at least 50%, and then heat treating the alloy to induce recrystallization. This combination of plastic deformation and recrystallization was found to provide desirable grain growth and microstructure. The resultant alloy is useful in a variety of device components, including transducers, frequency filters, signal delay lines, and optical fiber grating devices.

    摘要： In accordance with the invention, an optical cross-connect switch includes an optical router for distributing multi-wavelength optical input signals, an optical combiner for supplying multi-wavelength signals at the output ports of the switch, and optical fibers for interconnecting the optical router and optical combiner. Selected interconnecting optical fibers include controllable wavelength-selective elements, such as magnetically controllable fiber gratings, which are capable of transmitting or reflecting individual channels within the multi-wavelength optical signals so that a selected channel of a particular wavelength can be routed from any of the input ports to any of the output ports of the switch.
