摘要： Devices are described in which certain crosslinked silicone polymers are incorporated. These polymers have various functions such as encapsulating agents, surface protective agents or agents to index match optical components (e.g. optical fiber, optical waveguide, etc.) to other optical devices or articles. The polymer is a vinyl-terminated dimethyldiphenylsiloxane copolymer crosslinked with tri- or tetrafunctional silanes in the presence of a platinum catalyst. The phenyl group content of the crosslinked silicone copolymer is adjusted to change the index of refraction of the polymer to the optimum for the particular application contemplated. Polymer preparation procedures are described which yield good optical quality for the polymer as well as optimum physical and chemical properties.

摘要： An optical coupler having an optical core in which a small concentration of refractive microparticles has been added to a suspension material of the optical core. The result is that light from an optical source is bent slightly by the refractive effects of the microparticles and is coupled into the higher order of modes over a relatively short distance within the optical core. These microparticles are closely matched to the index of refraction of the suspension material resulting in smaller deflection angles and fewer reflections. In addition, these microparticles match the specific gravity of the suspension material such that they do not settle out of a suspension while the optical core material is being hardened from a semi-liquid state.

摘要： The process is provided involving formation of multilayer components in which a photoresist-type material is used not only as a conventional patterning material, but also as an insulating and/or planarizing material between magnetic or electrically conductive layers. A variety of integrated CMOS/micromagnetic components are thereby capable of being formed, including components containing planar inductors and transformers. Additionally, a particular technique is used to etch gold-containing seed layers from a substrate surface without damaging an electroplated copper coil. Also provided is a magnetic material particularly useful in devices such as inductors and transformers. The material is an amorphous iron-cobalt-phosphorus alloy having a composition of CoxPyFez, where x+y+z=100, x is 5 to 15, y is 13 to 20, and z is the remainder. The alloy typically exhibits a coercivity of 0.1 to 0.5 Oe, an electrical resistivity of 100 to 150 &mgr;&OHgr;-cm, and a saturation magnetization of about 16 to about 19 kG, all of which represent improvements over Permalloy.
