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： 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 is a reconfigurable optical grating device using force from programmable magnets to alter the mechanical strain, preferably a tensile strain, on the gratings so as to induce a latchable change in grating periodicity using a pulse or short-duration current. It includes apparatus for limiting the maximum strain applied to the grating so that the fiber does not fracture, and it provides strain without rotation or twisting of the fiber grating. In preferred embodiment it provides control of magnetic force so as to accurately obtain a predetermined amount of strain and hence wavelength shift in the grating with a minimal amount of electrical power. The inventive structure is useful, e.g. for wavelength division multiplexed optical communication system comprising wavelength channel add/drop devices and/or dynamically gain-equalized amplifiers.

摘要： A tunable optical grating device that can be digitally and latchably tuned comprises a length of waveguide including a grating region, and a movable body and fixed substrate attached to the waveguide proximal the grating region. The body is movable from a first position to at least a second position, and in some embodiments to a plurality of positions, along the length of the waveguide to apply a mechanical strain to the grating to shift the wavelength response of the device. The movable body is latchable between the various positions along the length of the waveguide to define a latchably tunable device so that a continuous supply of power is not needed to tune the device. The digitally and latchably tunable optical grating device is useful in WDM communication systems, particularly for adding or dropping channels and for dynamically gain-equalizing optical amplifiers.
